I've been on Lamictal for about a month now. Started extremely slowly at 12.5 mg, now I'm at 25 mg. I've had minor side effects (cramps in my calf muscles, esp., muscular and joint pain, but not strong). I did have crying spells in the first few days, don't know if they happened because of Lamictal, but it seems likely.
Looks like it's working so far. My mind feels lighter and the mood swings are becoming less severe than before. I've started to think about new work projects I'd left aside before due to depression.
I have been recently diagnosed with cyclothymia, rapid-cycling, with mostly depressive rather than hypomanic symptoms.
