High humidity symptoms and conditions

In July I was prescribed Lisinopril / HCTZ 20 /12.5. Within one week I started to have side effects. These included
-pain in chest - worsened with high humidity
- trouble breathing - shortness of breath - worsened with high humidity
- slight continuous elevated temperature about 99.6 degrees
- near real fainting spells when outside in heat- granted it was hot, but I've never had these before
- loss sex drive
- urinate often
- don't sleep well
My BP did go down though about 10 to 20 points.
still that was the worst summer I've ever had.
After reading others' side effects, I stopped cold turkey and feel much better.
Did you know Lisinopril is extract of Brazilian viper venom? - no wonder I couldn't breath!
My new doctor has me on new drug: Amlodipine Besylate 2.5 mg. which I hope will do the trick.
Bottom line:if you have bad side effects stop and try another drug - there are prenty out there for BP control.
