I just ordered some inositol and thinking to get on metformin for my PCOS for fertility and weight loss. Since diagnosed with PCOS I've gained 20lbs, energy is always running on low and of coarse still no BFP:( I'm just feeling on low and the gaining weight is no help! Has anyone had any success with the two meds above combined?
