Propecia gave me sides, try Avodart???

[Aek]

A few years ago i tried propecia (1mg per day) and got side effects after 4 months, so i stopped and it took while (6-7 months) to get back to normal (80% better)
After 2 years i tried it again but 0.25mg every second day, Took it 3 times and noticed i couldn't get it up. So I've stopped. Slowly getting better.

Has anyone had sides with propecia and then tried avodart and was ok?

Should i try Avodart 0.5mg (per week) or am i just going to be playing with fire??
