My story:
I've been taking 1 - 1.25 mg per day since 1998. I'm 34 now. Over the years I've had no problems sexually besides a slight lower libido, watery semen and things like no morning wood. I honestly didn't care because I could rise to the occasion easily and to me that wasn't a problem. Sometimes I took supplements to increase libido and that seemed to help actually. You can get lots of natural supplements online. I won't post any name brands cuz I'm not a shill.
I did start to have depression / anxiety problems over the last several years and lately its been particularly bad. Just problems focusing and concentrating. I just rolled with it and didn't let it bother me but now I'm sick of feeling spaced out. Sometimes I would feel fine but other times just totally out of it. I live a healthy lifestyle with eating and exercising but I still would get the foggy feeling. I've taken anti-depressants that didn't really help but I noticed that taking clonazepam really helped clear my head though.
I'm hoping to lower my fin dose but I might just quit altogether as I'd rather be able to think straight. I don't know if fin is to blame for my psychological state but perhaps over the long-term it has played a role.
My plan is to quit for a while (probably lose hair

..) and attempt a natural regimen. Once my head is straight I will probably start fin at a lower dose.
I think you can gauge the level of how much fin is affecting you by whether you have morning wood or not.
I don't like the idea of being off fin because I think it has really helped my hair over the years! So hopefully I can get a lower dose that works for me.
I'm also NOT yet convinced that my mental state is from fin because:
1. All my docs including psychiatrist have said it wouldn't give me depression/anxiety
2. I have friends on it and are fine
3. I have depression / anxiety in my family
Anyway I'll be checking to see if you find a good dosage. I read that .2mg every 3 days is pretty good.
