depression
"Note - I take Lamictal for treatment resistant depression, but that wasn't offered as one of the condition choices.

Lamictal has been a godsend. My p-doc prescribed it to augment the Effexor (300 mg/day) that I take. As others have noted, you have to titrate up gradually on Lamictal so it can take about six weeks (in my case) to start seeing improvement. At 75mg/day I definitely began to notice a change for the better and at 100mg/day (which I've been taking now for 2.5 weeks) the positive impact has been dramatic. 

I don't wake up every morning plagued by anxiety and negative, self-loathing rumination. I am actually happy which hasn't been the case for many years."
