Well I'm dealing with all of the above. I went straight to 20mg for a 145/90, I feel like CRAP. Back pain, dry throat, feeling like I must breath deeply, insomnia. Last week the sweaty palms and lack of hunger around noon time started (I talk it with dinner). I like to have a few drinks at night and initially I thought it was alcohol withdrawal, funny it started when I got on the meds. Anyone else with a similar story? I haven't taken it today and we'll see how I feel tomorrow.
