The following is from my personal experience and is my opinion. Starting in my 30's, my shitty diet of fast food and too many carbs caught up with me. Typical American crap diet, fairy tales like the food pyramid that I believed at the time. I gained weight. My BP rose, at the highest, it was 160/100 untreated. They started me on Lisinopril/HCTZ. I got the cough, it was horrible. I put up with it because I didn't know I had alternatives. Between the weight gain (metabolic syndrome) and BP combo drug, 90% ED. Never could get completely hard after that. For years in fact. Gradually I did more and more research, turns out HCTZ is a known big-time erection killer. Fast forward many years and lots of reading.....Losartan is the best BP drug with the least side effects (but every drug has sides, and I mean every drug), it does not affect ED, in fact, it can make it slightly better. And as for me, the best drug is no drug. I lost 60lbs (KETO), weaned off the BP drugs, added arginine and citrulline, daily Cialis, and became more metabolically healthy via diet. It can be done. Having to take a BP drug or a beta-blocker (and a good many other drugs as well) is not conducive to a sexual lifestyle that involves penetration. Just saying.
