anxiety
"Just started Pristiq yesterday. I'm taking it to replace Cymbalta which I gained 10-15 lbs on in two months. 60 mg of Cymbalta was awesome for my anxiety but the weight gain was antagonizing my depression. I also take 200 mg of Wellbutrin SR and have taken that for a long time. 
I've been a little jittery since starting the Pristiq and spent some time in the bathroom last night. I'm coming off Cymbalta slowly over the next week so right now it's hard to judge how the Pristiq will work. I take Xanax as needed and took some today as I was feeling tense. I attribute this to the adjustments I'm making. Glad I picked Labor day weekend to make the switch. I'll keep you posted on how it goes."
