Side effects or mind games?

[JNorton52]

I started taking generic fin three days ago, and I'm only taking 0.5 mg a day. I was terrified of taking it because of all of the propecia hate and life ruining ive been reading about. I finally decided to take the plunge, but I've resolved that I will immediately discontinue fin the moment I noticed any side effects. However, this has gotten me searching for side effects, and when I look for any testicular discomfort... I WILL find testicular discomfort. I've noticed that my testicles have been hugging a little closer to my body lately, but I can't tell if that's just my paranoia or not. Basically, I'd just like to know which side effects I should be on the hunt for. Is it just enough to be monitoring things like erection size, semen quality, and to check for gyno? I keep reading that fin is sinister and I may not be able to notice the damage it's doing to my body. Ugh, the Internet man...
