I've been on lamictal 150 for years and have had no side effects. My husband and son are both also take lamictal 150 or 200 mg. It seems to be the first med try here. I noticed a difference in my son when he got to 50 mg but nothing until at least 100 for my husband. I had no side effects and only take 1x a day. Currently my husband and I take it in the morning. My son takes it at night.

Its half life is 14 hours so about 14 hours after you take the 100mg you only have 50 mg in your system.

You have to worry about the sjs rash that can be deadly when you first start and when upping your dose but all meds can cause that.

Depakote is one that they use often I had no problems but it was 2x a day . I eventually stopped taking it (to the dismay of my pdoc)
