For me I avoid Caffeine to Prevent Arthritis Pain! Two days strait of use I can really feel it in my joints. When I drive a car for long distances (two hundred or more miles) I drink coffee/sports drinks to stay awake. When I get home it's hell for at lest a week getting off of it. Withdrawals in tail many bad headache and it changes my mood making me depress for about four to five of the days.

Bottom line, caffeine is a drug that I use only when I have to and it hurts me a lot to do so.
