I really felt great on Zoloft. Decreased pain and anxiety... less fatigue except I needed a nap. Then I had severe stomach pain, developed GERD (had acid reflux previously). Even on Protonix was bad symtpoms so I quit the Zoloft after one month after a few days of severe stomach problems. Now everything has gone backwards... I am having severe lymph node troubles in my neck. They are huge, painful and persistent. I am so tired and achy. I have not been this bad in several years!! So was the zoloft just temporarily making me feel good but really reversing everything in the process? Man can't find anything to help this DD!!
