Thanks everyone for replying

I guess I'm hoping that just 25 mg CAN have an effect because maybe that would mean this feeling better thing won't just up and leave suddenly...either way, I'm going to continue to increase slowly and just see what happens - very thankful I've had ZERO side effects so far.
@NeatFreak - when did you decide you were on a high enough dose?
@Christina - I have never had to go off lamictal before, no. I have had to go off SSRI's and benzos - both awful even though I went ridiculously slow.
