I take diazapam before I go to bed to help me sleep. I also take meds for high blood pressure and class 2 diabetes ( torsemide in the morning and glimipiride) and (doxazosin mesylate andlovastatin at bedtime) I wake numerous times through the night with dry mouth and have to get up to go to the bathroom and also get a drink. Probably 3 or 4 times in a normal night. Could one or more of these medications be causing this? I also take metformin twice a day.
