I'm on Animal Pak, I got 45 more days on it and then I'll be switching to something else because of cost. Even though is it just like 25 dollars with shipping, because I order 3-4 things at once, I think I can find something cheaper somewhere does the same thing.
I have noticed I wake up easier on it most days, some days I am completley shut out but the more and more I take it, the more I go without having too much trouble waking up. We'll see I reckon. I may not switch if it gets better by the end of the 45 days.
