It is important to realize that everyone has a different reaction to medications. If this is understood, it really would not matter which types of reactions others were experiencing.
That said, I am happy to share my experience. I have found Lamictal just fine for energy level until I hit 400mg/day. I am fine at 300mg. I am exhausted and dizzy at 400 mg. It is important for me to add: I take several other meds related to painful autoimmune conditions. It is likey these med interact. with Lamictal.
I hope Lamictal will work just fine for you!
