Advice as I prep for IVF

Hey all, my fiancé and I will be starting the IVF process after our wedding in October (I've gone through about 2 years of testing - PCOS, adenomyosis, and both tubes blocked will make it impossible for me to conceive on my own). Does anyone have tips for lifestyle choices in the months leading up to IVF to try to increase our chances? I'm eating healthy and exercising but am wondering if there's anything else I should focus on or avoid. Does cutting alcohol make a difference? Or avoiding certain foods or meds? I've heard different things from different people and doctors so I'm wondering what you've all been told. Thanks in advance!!!
