But, bombscience... are you single?
spironolactone might be okay for someone to use if they are single, but if you are married or live with someone then the choice to use spironolactone is really a choice that must be made by both people. Leaving aside one's personal taste for HOW spironolactone smells, I think we can all agree that spironolactone DOES smell.
This taken as a given, then you must agree that spironolactone is something that really can't be hidden from someone you live with? When/if you decide to make that decision (if you haven't yet), then are you prepared to sit your sig other down and say, hey by the way, there is this stuff I put in my hair, and it kind of has an odor...
