(not sure if this is the right subforum for this)
I've been taking it for about a week and haven't had any bad side effects, just minor constipation, and twice now I've been nauseas just after taking the pill. I think
that both times it happened I had taken the Alli and then not ended up eating right then, so maybe that has something to do with it. Nothing big, though—definitely not enough to turn me off.
I know the opinion on Alli is kind of mixed, but I have definitely been eating less-fatty foods because you don't really have a choice, so I think that alone makes it worth it. I don't have a whole lot of willpower, so Alli kind of forces me to eat better, which is good.
