Propecia and 20 years old

I have never experienced a feeling like this before. I had vivid, unexplainable dreams. The first night taking it, I had a strange feeling in my throat and woke up almost choking(that was on the list of side effects, closing of the throat. I kept myself up all night and now I feel like yesterday and today was one big long day. Now I'm getting the feeling again while I'm awake and am afraid to go asleep. I also felt very, very weak and dizzy all day. This is not worth it, I want my old self back already and this is only my second dose. I read up on Shen Min DHT blocker and want to give that a try. I'm 20 years old, have long hair and want to keep it, I love it like a child.
