i am on it for past 2 weeks will double to 5mg today, it gives u serious dizziness when u r new, its on prescription to use it only after dinner, then after few days take with breakfast. it does normalizes your sexual system particularly morning erections also mood enhancer IMO. i paid about 10$ for 30 2.5mg tabs.
for lowering prolactin (not progesterone)2 week course is recommended.
