Depression
"I&#039;m 22, and my doctor changed me from Effexor to Pristiq for my OCD and OCPD. Most noticeable side effect is definitely the appetite loss, but I don&#039;t seem to be losing much weight thankfully. If I&#039;m busy and don&#039;t think about it, I go all day without food- it&#039;s nuts. Also I am having a lot of headaches, but I cannot be sure its the medicine. I sweat A LOT on this, and if I take it too late in the day I cannot sleep. My OCD seems to be in check- much better than Effexor. I&#039;ve been taking 50 mg for 5 months now."
