I noticed this first last night after a glass of wine. My stomach felt tingly or cold. Not my upper GI area like heartburn or anything, but my stomach. Then again today after drinking some water and again after lunch. I can't explain the sensation very well, except that it feels cold or tingly...

Any idea what could cause this?

I'm on Zoloft 50mg for GAD and Aciphex 20mg for GERD.
