I only drink 1 cup of coffee a day or I get more tremors than usual in my hands. Sodas are out for me as they actually put me to sleep instead of give me the jeeters. As for credit card companies calling you when you order something online that isn't a usual product, I'm glad they keep an eye for us. I got a call when someone out in CA (I'm in IA) tried charging $5Gs for stocks to my card. On another card someone tried to order $1,800 worth of makeup at Sephora on it. Never use that card for Sephora and if I needed that much make-up its time to pack it in and give up.
