Nebivolol
"I am a 43 year old male. I recently was diagnosed with high blood pressure 190/104. My doctor started me on 5mg per day for the first month. Raised it to 10mg per day on the 2nd month and 20mg per day on the 3rd month. Recently I started having random and uncontrollable bouts of diarrhea. I am also tired all the time with low energy levels. I am an Electrical contractor, before I started taking this medicine, I was a high energy, multi-tasker. Now, although my blood pressure is under control, I am tired most of the time and at times I can't seem to think clearly enough to perform the complex logical tasks that my job requires. The Diarrhea is sometimes UNCONTROLLABLE."
