I have been having some similar symptoms, and suspect alcohol to be the cause. Have an EMG, but physical exam and blood work all came back normal.

I have dialed any drinking back big time, but have a glass of wine or two every once in awhil. CTman, I have read the same things about any alcohol making it worse, bur just wondering if it is a reaction to the alcohol vs the PN actually getting worse. Clinically speaking, I don't think moderate to low amounts of alcohol can cause nerve damage.
