Thanks for your helpful words, Ank.
Yes, the mental health community isn't a perfect place. Last Spring, my GP diagnosed me with dermatographia and put me on Cetirizine, then switched me to Fexofenadine. These have helped. Also, I've been off Lamictal since end of past April. I've started getting comments from Mayo readers concerning posts I made almost a year ago! Some kind of tear in the spacetime continuum?

Thanks again!
