If I switch from 200mg of Spiro per day to 100mg, is that going to cause the androgen induced (not sure what to call it) "problems" I had to come back...for example will my skin become oilier or will my body hair go back to normal?

It did with me. 100 mg was not enough for me. Granted, I'm buying my Spiro from overseas. You get better quality assurance in the U.S.

Actually, lowering your dosage won't "induce" anything, it just may be less effective. But, it may be that 100 mg. is all YOU need. Give it a try. I say take the least amount possible. 100 mg. is still far better than none at all.
