high blood pressure
"I feel better in general, however there are times I feel awful, and when my BP was tested during one of those times it was lower than without meds, but still too high 140/90. However without meds, I feel awful all the time. 

Side effects include leg cramps, calf twitching, and excessive urination. Cramps are semi-relieved by staying hydrated. Tiredness and dizziness stopped after the first couple days. 

I am on the lowest dose, I suspect my doctor will increase it a bit."
