M.H.
levora is stronger than OTC Lo, if i recall. i'm not surprised it makes you nauseated. taking it at night can help, actually. in the end, if the symptoms are such that it makes you not want to take it, it's not the right pill for you.
for very mild symptoms, yes, a few months is realistic, but daily gagging isn't mild to me.
a paragard IUD would eliminate hormonal issues as would TCOYF, but there is what some consider a huge time investment in fertility awareness (daily temping, charting, cervical mucus, etc.)
the pill Cyclessa hardly gets a complaint where i work (planned parenthood) and the practitioners have nothing but positive things to say about it. that doesn't mean it's the right pill for YOU, but it does seem to have a good track record w/a lot of folks.
hope that helps somewhat.
