I started taking it two weeks ago and am supposed to increase from 25 to 50 mg tomorrow. I'm thinking about stopping it b/c even at this low dose I feel pretty flat, too. I usually take antidepressants with antipsychotics and don't feel flat at all, so I may ask my doctor about switching up my antidepressant or antipsychotic soon if I discontinue Lamictal. I have mainly depression but occasionally have some hypomanic irritability (not often, though).
