After being on 25 mg for two weeks, I've now been on 50 mg of lamictal for almost two weeks. I'm going to move to 75 mg soon, which (according to my psychiatrist) is when I should start to feel something.

Just wanted to know what everyone's experiences were. I've had some pretty terrible experiences with medications in the past. Zoloft made me go manic (which is what caused my psychiatrist to realize that I probably have bipolar tendencies). Another one which I've had (I cannot remember the name of it -- it had two names, one started with an "m" and the other with a "r") caused weight gain.

My main worry is any side effects -- particularly weight gain. I've gained the horrid freshmen 15 after starting college. Also, I've gone off of my Dexedrine (which majorly suppresses appetite) -- which I've been taking since I was eleven years old. It's hard to manage my appetite now that I actually feel hunger.

I've also heard that lamictal can cause lethargy. I've actually been experiencing issues with insomnia (which I'm now taking ambien for, which I hope doesn't cause weight gain as well) and briefly went off of lamictal because I couldn't sleep. What have been the experiences of people that were made more energetic by lamictal? Did you still get the whole "brain fog" or anything?

At what dosage did you guys start to notice changes? If it helps, I'm 5'3" and about 121 pounds -- in case my size would have anything to do with what dosage would affect me more (sorry if this is unnecessary information).

When should I start worrying about the dreaded rash that I'm always told to fear for? I haven't gotten anything so far, but am I at too low of a dosage to feel safe about not having had any rashes?
