... experienced and wondered if it could be result of MS Contin. 6 weeks ago I switched from oxycontin to ms contin and depression is getting worse and worse. I don't know how much more i can sink... I did start back on wellbutrin but it's not helping, but its only been 3 weeks. I'm scared. I don't even want to talk to my own mother, and just want to lay on bed and sleep. ANYONE?
