I used to quit drinking coffee quite often just so I knew I could. Even after getting the RSD I quit on doctors' advice but it didn't make any difference each time so I started again. I tried to quit last year and for the first time couldn't do it. I started getting a mild panic attack and it wouldn't quit till I had coffee.

It probably doesn't matter. I'll try to quit again.

Alcohol interferes with a couple of my medications but I don't really miss it much. It washes vitamins out of the system and causes other mayhem anyway. The biggest problem is blood pressure soars with even small amounts usually.
