erectile dysfunction
"I used to take Viagra on occasion and it worked great. I even was able to split 50mg in quarters. Doc recommended Cialis at 2.5mg first. Took for 2 week no results. Then he gave me 5mg and he said I can take up to 4 5mg at a time. Still no where near the firmness of Viagra. It took hours to start working and firmness would last about 5 minutes. I could get hard again but I'll lose it fast. Goes to show not all meds work for all."
