How long have you been taking your new meds? It takes a while for them to start working. I'm on lamictal as well, and it's been working pretty well although I did have to go up a little on my dose a couple weeks ago. Everyone's different so you never know... If lamictal doesn't work you can always try something else.
I'm sorry you're feeling bad, that's no fun

but hopefully your meds will start working out soon
Good luck!!
