Lisinopril Calcium Channel Blocker, Post Partum Depression, Loss of Concentration, Severe Headaches, Loss of Sleep

I developed hbp during pregnancy with my first child, after delivery the bp continued to stay up for about four months and then it went back down to a safe level. Six yrs later I became pregnant with my second child and my bp spiked again. Once again, after delivery, my bp went even higher. I tried a calcium channel blocker which gave me SEVERE headaches and then was put on a beta blocker. The beta blocker had no side effects but my bp was still out of control. My GP tried me on Lisinopril 10 mg in November 07. Since then I have had abdominal pain, loss of concentration, fatigue, leg and arm pain and numbness that is slowly worsening, dry, hacking cough, loss of sleep, strange thoughts of losing family members, etc....When I spoke to my GP about these new symptoms, I was told I have reflux, even though I never get heartburn and get this...POST PARTUM DEPRESSION! Oh, I am so sick of the "D" word. I never have thoughts of hurting myself or my kids, not to mention, I'm the happiest person I know. I'm really convinced now that these symptoms are all due to the Lisinopril b/c it all started around that time. The cough can be so embarrassing. I work in health care and will start hacking in the middle of an exam with a patient. It comes off as really unprofessional and it bothers me a lot. I see him next week and will discuss this with him. I am kind of discouraged b/c my bp is totally out of control w/o meds and this is the second one that has caused major side effects that has actually helped my b/p.
