Dude I was actually thinking about L-Dopa as well!
I started propecia back in 2010 and quit in 2018–I’ve had PFS since then and it hit me around 2014 and then I crashed in 2018. The sexual and mental sides are kinda the same and no change. Sexual desire is not there and I still get depressed often BUT, I find those happy moments to come around more often but they are very short lived.
