Hello and I to have experinced the same as you and really gone through many AD meds. Right now I am on Effexor but it was not holding on it's own so I finally agreed to give Lamictal a chance. I am up to 50 mg per day and it is working. I will be at 100Mg next Friday and I expect the therapuetic effect to be even better.
So far this drug has work better then anything I have been on over the past 5 years. I have major depressive disorder. So please wean onto the medication slowly and give this one a chance - it has really balanced my mood and the constant feeling of sadness.
Kindly,
Kitt
