I have been on Propecia for 6 months I am a diffuse thinner in a NW6 shape.
My personal advice to anybody taking Propecia and its side effects is not to think about it. I believe the mind is a very strong thing and this can play a huge part in so many people getting side affects.
for example I rember my first time it was with a women ten years older than me I was shitting myself I had problems
the same with the next girl and so on until I said to myself to forget about it and hey presto no more problems.
When I started the drug I had loss of libido etc etc tehn I again said to myself forget it im gonna take the drug for 12 months to see what happens as soon as I stopped thinking about it the problems went away!
Im not saying the side effects dont happen at all but I believe that 90% of cases are due to the mind and over thinking about it I would be interested to see what would happen if people took the drug without knowing of side affects or what the drug was even for.
