I've been on lamictal for about 4-5 yrs and find it flattening too. In a way I like it because it allows me to take the emotion out if a problem and just look at it logically. On the other hand it does make my hubby really wonder if I actually feel love for him, or just like. I'm not a very demonstrative person anyway, and then there's the flattening.
Also I sometimes wish I feel more... umph about things. Get more excited.

Buuutttt.... since I'm bp2 and tend more towards getting in a low funk than hypo, I spoke it's the lesser of two evils. ��
