The finasteride is already out of your system and you’re on the hormonal roller coaster, no need to amplify the effects. Furthermore, there is a greater chance of increasing the side effects by taking finasteride again. Some people don’t develop sides the first time they start and stop, or some people develop sides the second time they go on and they never go away.
IMO stay off and study some healthful living options and hope the sides resove over time, they do for many.
Paleo diet, get enough sleep, no stress, avoid excessive masturbation, no alcohol, sugar, or caffeine.
