Long story short, I've was thinking seriously about quiting before I did. Oddly enough I was at a drug store and saw the patches were on sale. I bought a couple of boxes and decided to quit smoking that day. Fast forward two weeks, I've smoked 3 cigs since the day I decided to quit. I think I'm doing fairly well considering I kind of started this half hearted. This morning I had the shakes something awful. I was on my last patch of 21mg or step 1. I had an upset stomach and rapid heartbeat also. Has anyone else experienced this? Was I ODing on nicotine? Should I step down to the 14mgs now? I don't want to give up on this attempt to quit.
