My psychiatrist prescribed Xanax (smallest dose available) to help me with anxiety that was preventing me from driving.
I took my first pill (at home to see how it affected me), fell asleep half an hour later and had one awesome nap.
Needless to say, I could not use it to help with my driving issues.
I probably would not have taken a polygraph test while on it, chances are I would have fallen asleep during it!
I don't know what CA is taking but I noticed awhile ago she seemed to have issues with dry mouth. Frequent gum chewing, always carrying a bottle of water, licking her lips and displaying other mouth movements that indicated dry mouth.
I don't know about other meds but anti-depressants usually cause me to experience dry mouth until my body adjusts to them being in my system.
Just my 2 cents.
