I need some uplifting words and maybe some advice. I was diagnosed with PCOS about 2 months ago after a CP. I have been on Metformin for 3 weeks now m. Started at 500mg and worked up to 1500mg I've been on for about 10 days. I had zero issues until I started taking 1500mg and now I feel awful. Cramps, nausea, bloating, some seriously toxic farts which is super embarrassing. I'm starting to feel like "Is this worth it?!" Please tell me these symptoms don't last forever. I've changed my eating habits, I've tried taking it one at breakfast, one at lunch, one at dinner, I eat 6 small meals and I just feel awful. Also, any success stories of getting pregnant on Metformin alone could cheer me up. 🤢🙁
