I think your medication is doing what it's made to do... Make you feel better. It may feel strange to you because you may not be used to any sort of 'normal' feelings, but you'll get used to it. I do understand why she would say cut them in half... Because right now you're on an extreme 'high' and that usually means that whenever you do get down, you'll go extremely 'low', and you need to be at a level pace. That's probably why she suggested the half prozac instead of a whole one.
