the medication does swell my sinuses  and gives me a mild migraine headache. Tylenol will usually fix this.  Like nearly everyone else, it works in about 30 minutes for me, but I  can become more normal and have more spontaneous control after about  four hours. There is also impact during the next twelve  hours. My worst side efect is shortness of breath. After taking the  pills for the first few times years ago, it seemed like there was  some permanent lung  damage. I never got my breathing back right.    As far as physical shape, I became a karate champion, placed first  and second place for two consecutive years in national competition. I  started this even after I contracted E.D. I hoped that this exercise  would help, but it has made no difference. This was before Viagra  became available in Mississippi, where I live. I worked out in the  gym — weights and treadmill, amino acid supplements, B vitamins,  kick boxing aerobics. None of this help.    Formerly, when I got really worked up and super-hard, one testicle  would retract up inside me. The doctors did not think that this  situation contributes to my E.D. However, I believe that this is a  contributing factor to E.D.    I am a truck driver, and I do have some minor back pain up the middle  of my back. I sleep in my truck quite a lot. I also also hold my  urine for long periods during sleep, and I have wondered if this  could be a factor in E.D.    I also do not have as much seminal fulid as I once did. I have had  some problems over the years with chronic urinary tract  infections. I learned years ago that caffeine, asprin, or B.C.  headache powder, when overused, can cause E.D.    This is my sexual history. I was a sexaholic before this  happened to me, Yes, I am negative for any STDs. That’s the first  thing the urologist checked.
