Penile erection symptoms and conditions

My bio stats: Male, age 41, bodyfat 12-15%, 5'8, 200lbs (I gym a lot). BP without medication range from 150-160/90-110.

Only started treating my BP this year.

Developed a persistent coughing immediately after taking Lisinopril (20mg). Coughing especially bad round 12mn to 4am before being able to fall asleep. Lost of strange and almost blacked out twice in the gym. Lost of libido and penile erection after about 2 months of use. Horrified, I saw my doctor and he swtiched me to Losartan about 1.5 weeks ago.

With Losartan (25mg) I developed a sore throat within 3 days of use which become a really bad chest infection a week later. This was 2 wks ago and I'm still fighting the chest infection with erythromycin and codine.

Obviously, this completely spoiled my gym workout schedule.

Also, I realised that about 4-5 hours after taking Losartan, I'd develop and really bad lower back pain (almost like a slip disk). It would go away after about 6-8 hours.

I never felt more sick this long. Is it worth taking the medications?????? Is there a way to do this naturally without drugs???? HELP!!!!!!

I'm almost ready to give up eating out and just making plain boiled chick breast meat everyday!
