erectile dysfunction
"My husband suffers erectile dysfunction occasionally, which is mainly due to his anxiety. He was prescribed Viagra and takes 12.5mg with water and on an empty stomach.  After about 1 hour he gets a great erection which lasts about about 45 minutes. This is great for both of us. The side effects he experiences are a mild headache and nasal congestion, which lasts for about 6 hours. I would highly recommend this medication but would suggest taking time to find the best dosage to suit the individual needs. We will continue with our current low dosage as this works very well for us."
