Hello all. I'm a newbie to Pristiq as I have only been taking it for 7 days now. However, in this short time, I've found that it has been the most effective of all the many different antidepressants I've tried dating back 20yrs. I'm also taking Levothyroxine 50mcg daily for HYPOthyroidism (4+ yrs now). I have found that my appetite has almost completely diminished and I've dropped approx 7lbs. Anyone else with a similar situation? Is this more than likely weight loss mainly due to the fact I'm in the very beginning of my treatment with Pristiq?
