depression
"I switched to Wellbutrin after a year of Zoloft mostly due to weight gain (I'd gained about 20 lbs. in a year). I started taking Wellbutrin 2x a day with a plan to eventually increase to extended release but the meds kept me up all night. I got maybe 4 hours of sleep a night even with Zzzquil. My sleep was extremely restless and I woke up about every hour. I called my doctor and asked if I could switch to the extended release version but she said it would probably be the same situation. I did like how the meds made me feel. Very little depression and I felt super energized and productive. Honestly I was almost too wired; I was very jittery and almost a bit manic."
