Rapid pulse, shortness of breath on exertion, kidney function tes...

I have been taking L for about a 9 months and dealing with many of the same effects mentioned on this board; lethargy (hard to get up in the morning), irregular heart beats, erection issues, loose stools (wiped my ass raw at times), limb tingles, etc, etc, etc. I forgot to take it yesterday, didn't take it today and wow, my normal bowel movements are back (one wipe ;o). I am going to stop taking for a while and see if the strange heart beats stop, Bummer of it all, is that the drug did wonders for my 190/80 bp. Within a week L Iowered it to 120/70. I have always been borderline (even as a high school and college athlete). I am guessing I will need to try another drug, but which one? I have actually tried others but none worked as well as L for the bp.
