Clonidine
"Clonidine  1 mg  x 2 times a day did not lower my Blood Pressure enough. It brought it to 135/95, (without medicines my readings are 160/110 ). So now I am taking it 1.5 mg x 2 times (morning and at bedtime), and waiting to see if it helps to get back to 120/80. I also take Cozaar 50 mg once a day. Yes, dry mouth is a slight problem. But I just carry bottled water wherever I go. Cozaar gives me diarrhea, and the clonidine has a constipating effect. So they kind of cancel each other out. Clonidine also gives me slight dizziness, especially when I bend down to reach for something, and then get my head back up. If the head is not subject to sudden motion, I really have not felt dizziness to be a problem."
