About 7 weeks ago I started taking zoloft for anxiety and depression. I started at 12.5 the first week, 25 mg the 2nd week, and 50 mg from then on. Things got a little better but not too much. On Monday, my doctor increased my dosage to 75 mg and will be going up to 100 mg this coming up Monday. The past two days I felt pretty good, but today I've felt depressed, lethargic, not motivated and a slight increase in anxiety. I was wondering if these are just normal side effects from just recently increasing my dosage. I hear some people say it gets worse before it gets better. I don't know if I should just give it time or go back down to 50.
