Before I was medicated, I used to not be able to sleep on a regular basis, easily getting under 10 hours for an entire week on occasion that it would be so bad. Falling asleep would be hard, and staying asleep even harder [waking ][/waking]. So good luck, with this. I havn't really felt any negative effects other than feeling like shit due to lack of sleep. 

but now I sleep easily thanks to my bi-polar meds Heh.

After a while, I started to hear conversations in my head.  Also, I'd get visions of movement in the corner of my eye where there was nothing.  It's not really vivid hallucinations, just your mind under a lot of stress, definitely not enjoyable.

I remember when I started my SEAMAN training they put us through a sort of sleep deprivation program for a month where we had to work in a galley all day from 4:00 in the morning and didn't get to sleep to about midnight, being on your feet all day busting your ass and then not getting a good night's sleep will take it's toll on you QUICK.

After the first week or two I started hearing this guy's voice in my head and all kinds of odd shit in general, I'd be sitting on my bed and would hear someone saying my name and when I asked the nearest person what they wanted they thought I was fucking crazy.

I didn't get that, that was what I was experiencing until now so thanks I don't feel as odd about it anymore.

I've done several 36s but it is pretty awful

Yeah, the most I've ever stayed up is probably 36-40 hours. My body is just not meant for sleep deprivation. 24 hours into it I feel fine, but at about 30 I start to really shut down.

Yeah it's just... not very fun, idk. When you're young it's HELL YEAH REBEL AGAINST THE SYSTEM but then you just stop caring about that shit. I always feel so dirty after pulling a 30+ hour 'marathon' and I can't feel clean unless I sleep for like 2 days. Even showering doesn't help that shit.

get a job

Nnnnnot worth it. Have you guys played a complete Monopoly match? Seriously, i had this most intense and epic Monopoly match with my friends during those two days. It lasted for eight hours (i recall? Guana was there too). After that i deciced i will not try 48 or Monopoly for a long time.

i mean jesus when you are a kid everybody just kind of give up at some point because nobody trades cards or anything. the official rules are very hc, the game is comparable to russian roulette.

Longest Ive gone for.. about 50-60 hours(Don't know the exact amount just know I went longer then 2 days) I was with some mates of mine and we all just decided to stay out for the night. Which then became 2.. then 3 haha. The first 2 days & Nights I stayed up but was feeling like shit(It was very cold and I had hardly eaten)and just caught the bus home.. And my GF at the time was pretty pissed at me for supposedly making her do it. She could have gone home if she wanted haha.

It was raining one of the night as well so we all just fucked around under the main bridge that connects Lower Hutt to Petone.. You guys have no idea what I'm talking about. Anyways good luck with this man and.. Don't try and cook around the 30 hour mark.

Huh?  Before I went to college I use to stay up for around 3 days playing online games, from my own experience I can say that the only times I can really recall hallucinating is when I was playing FF Online back then and I was playing but I was looking at my hands while playing (PS2 version) and I remember recalling looking at the chat battle logs and able to see when refresh ran out on the paladin and white mage or black mage or whoever was in the party. It was like my mind was so fixed on doing the same repetitive action that I unconsciously got the timing down perfect as to when the refresh buff was running out.

I also do remember one night of doing drawings and I have a pet peeve believe that if I go to sleep before doing a really good picture I will lose all the motivation and energy to finish it the next day, so I stayed up for around 4 days drawing something and looking at blue orbs flying all around my room… probably being at the computer so close for so long. There us also that annoying thing as to when your eyes have blood on them and itch and every time air hits them you want to blink.  Energy drinks make me go to sleep really badly, but the energy shots seem to work pretty decent if you get the right ones, I do recall those extended me for some hours and I didn’t have a crash effect afterwards.

The aftermath for me is normally really deep sleep and then waking up feeling weird, like my body has extra weight or something, but my mind feels light headed and I normally am sluggish for a few hours, I miss those days. Anyways, it really will mess with your sleeping habits, my only way to fix that was to force myself to sleep during the night so I wouldn’t end up waking up at night like I normally do if I where to stay up like this again. And… doing something you truly absolutely enjoy will help you stay up, I use to lose track of time playing online games and the sun annoyed me at around 6 a.m, btw the sun will hurt your eyes too. This is just based on what use to happen to me it  might be different for you or something.

Cocaine.  You won't sleep on cocaine.  You'll just want more cocaine.  You won't sleep until you're out of cocaine.  I'd suggest dropping 300 bucks on a bunch of cocaine.  I'd go through that much cocaine in a day but if you've never done cocaine you'll be able to make it beyond 48 hours..... on cocaine.  Don't worry no one will notice you're high on cocaine, just say you've been up for as long as you have been and you'd never do a drug like cocaine.

Cocaine.
