I've been on it 7 months and it has been a godsend, but lately I'm doing things that I wonder if I'd do if I were not on it.
I'm functioning great at work, and the stress is no longer crippling me, but I'm noticing that I'm following my heart much more than I would normally (rather than doing what is logical.) I'm not so sure this is wise.
I'm thinking it may be the "don't sweat it" attitude that Pristiq gives you - the ability to deal with stress can also make it so that you don't worry about the negative consequences to doing something you want to do but isn't wise? Takes away self control?
