ive been inconsistent with finasteride in the sense that i tend to take a couple days off here and there, sometimes even a full week and when i am consistent im always playing around with the dose between .3-.75 daily. Side effects did effect me in the beginning but now i feel pretty stable, still have great sex, but my fapping has went from once or twice a day, to once every 2 days. For what its worth, finasteride has effected my desire for fapping, but i still get raging boners when im with my girl. This is actually beneficial for me because i literally used to get so distracted due to my high sex drive, i now focus better at school and when im working with clients when running my business.
Truly i believe finasteride could be taken maybe 10-13 times a month and you can maintain your hair fine, I havent lost ground really but i havent gained much but im ok with that considering my quality of life isnt effected.
