Had to stop the drug after 5 days. It was making me feel so incredibly bad and sure I was getting ready to check out. I did not have the cough, but did have the insomnia, muscle ache and cramps, made my lightheadedness which is bad really, really bad. I was getting abd cramps and the eyesight was getting strained. AND, the BP really did not improve. I stopped it, and the PVC's I have were so persistent and unpleasant I did return to my 25mg of toporol XL which I would prefer not to be on. But, I have to be able to function at some basic level. UGH. Liam
