I'm pretty sure that thing about Aloe Vera reducing metastasis and all is bullshit... However, I know there have been clinical studies regarding its effect on side-effects (A nurse told me about this back when I was in high-school, when I first found out about my father having cancer)
Long story short, we managed to get some Aloe and religiously fed him it (Yes, it tastes like shit, i.e. is really bitter) and he barely had any side-effects at all with the chemo.
He didn't have nausea, he didn't get diarrea, he didn't vomit, etc.
...And he was on methotrexate, one of the strongest chemo cocktails there is.
So yeah... You'll probably hate every last drop of aloe, but on the other hand... It'll make it all alot easier on you.
Also... You can mix it with honey to make the taste more bearable.
