It does the job of lowering my blood pressure. Before it was high. I was also on Atenolol before but switched to Lisinopril/hctz 12.5 mg. While the med works I can't help but wonder how I've gained almost 50 lbs. in a year and I've followed cardio and weight lifting (Power 90) and eat primarily a vegan diet. To note, I was around 220 last year (I was 206 in 2011), also around the time I got on lisinopril/hctz but gained almost 30 lbs. in a year and it's frustrating. It seems most of what I have is water weight all the time. I don't understand. Part of the weight gain can also be from muscle gains. The only "real" fat have left is my around my belly and my arms are pretty much toned.
