I know how you feel- it's like my doctor had me on 1000 mg of met and 25 mg of spironolactone. So I told her after two years I felt nothing- my face is still hairy- and I feel nothing from the met except for nausea lately. She said she didn't want to up my levels- I told her fine I'm not wasting my money anymore and since then have been off the meds. Now I'm not telling you to get off the meds- but with feeling like vomitting daily, and then not seeing any change in hair growth- I just got tired of the meds.
Funny thing is when I got off the met I lost another pound and since then no more nausea and it even seems the hair growth isn't so bad- I don't know how that makes sense- but I'm guessing with trying to follow "The PCOS diet" as closely as I can- I've been able to control things that way. You can buy the book at amazon for like less than $10 I believe

It's a blue and yellow book.
Anyways- if you feel you need to see an endo- then do so. I'm sure they can help. I have a coworker on 2000 mg of met and 200 of spirono. She gave me her doctor's information and I figure if I keep losing weight and I'm still having a hair problem I'll either go see her doctor and get back on spirono (or if I'm rich get laser hair removal lol).
