well i have stopped finasteride for more than a year as well. i have the same problem that ttroy has.
chancer, if you are really that concerned, maybe get a hormone test before you take the drug, if you can.
maybe start the pill at half the dosage (buy a pill-cutter at a drug store) and see how you go.
like most users, you may not get any sides at all.
if you do get sides, and they don't disappear within 1-2 weeks of starting, then you may have an issue.
i made the mistake of continuing to take the drug for 4 months thinking my sides will go away during that time.
