Welcome Angelz,
I was on Lamictal for almost 2 years in the past, but not Risperdal (Dr. put me on Abilify instead). I have been on other various antipsychotics though. Sorry I can't be much help.
Lamictal is a good medication, just not the one for me. I'm on Lithium and Geodon at the moment.
As Serafena said, things get better over time. Hang in there!
