Most people don’t experience side effects at all. Some (more than Merck says as told by a doctor) get side effects stop using the drug and the side effects go away. A several thousand of us world-wide get side effects, come off the drug, side effects get worse and do not go away at all.
You are playing with fire. You may or may not experience side effects from this drug, its up to you to decide if your hair is important enough to you that you will risk having your entire life (not just your sexual life) ruined by this drug. Many people here may even be kind of insulted that you would post here while you are still on the drug, you have to understand there are men here who have lost everything because of finasteride. Its not only your dick that gets fucked up, your mental well being is also at risk.
Everyone here including myself are going to tell you to get off it, its simply just not even remotely worth the risk. If you come off it and are experiencing side effects a month later then by all means come back here and join the miserable club of PFS.
