Metformin?!!! Have you.....

Geriuana • Mother of #1 prince ( Demari )💙 |Baby #2 on board 💗| Madly in love with my best friend 👨‍👩‍👦.
Has anyone taken Metformin? I don't have pcos but I do suffer from insulin resistance due to weight & which ties into my lack of vitamin d. If you have, have you notice anything from taking it? Has you body change, do you feel different, change in weight? I know everyone body is different but I just want to know something I may or may not experience. I would appreciate the feedback. 
(Still trying to conceive) 
Thanks 😊
