They're putting me on a 24 hour monitor tomorrow, just to be sure.
(Personally, I think I just got over-excited at the TT preview and threw myself into a state! LOL)
By any chance, have you been taking any medication containing ibuprofen in large quantities lately? Or have you had a cold and were taking Sudafed? I ask because a few years ago I was having trouble with my left shoulder; doctor thought it may have been an ingury from doing some muscle building excercises with the stretchy band thingy. So he told me to take 3 Advil, 3 times a day for a couple of weeks to reduce the swelling. By the end of the second week I had developed serious heart palpitations. Called the doc and went out immediately, they did an EKG and it was all over the place! I was fixing to travel down South, so we planned to do the 24 hr monitor the following week. I had stopped the Advil the day I got the palpitations, and never got them again after that. When they did the monitor, everything was normal. I told the Doc I thought it might be the Advil, but he said he didn't think so(Hah!) I had talked to a friend on the day I had the monitor and told him what had happened. He said the same thing happened to him, but after having taken Sudafed.
To make a short story long, that's why I asked about those two. And lowering the caffeine intake wouldn't hurt either. When I make coffee in the morning, I use 2 scoops of regular and 4 scoops of decaf for a 12 cup pot of coffee. It makes 8 'vats o coffee'; we don't use cups! LOL!
