Myo-inositol questions

Ladies I need some advice. I have no insurance to get to the doctor, I have pcos and have been having issues with my period and infertility. I have heard that there are things that help (birth control, medicines, etc) but most of those things have to be prescribed by a doctor. I have done research and have come across a few over the counter options and myo-inositol seems to be the number one rated option.

Anyone try this one with success? If so what brand works the best?

I have seen the pros and cons of myo-inositol and I want to make sure I’m taking the right dose and a brand that actual works.

Please help. I’m so desperate at this point just to get some sort of relief with the crazy periods. Please no trolls or negativity. I’m just looking for opinions on medication not life advice. If all you are going to say is “go to the doctor” or some other non useful comment just don’t bother commenting. Thank you!
