FIRST IVF in August

Will be starting my first IVF in August after TTC for 5 years and 2 failed IUIs later. Looking for any advice for anyone that has already gone through IVF. I am currently on birth control and will start with Stims mid August. So if anyone has tips on what I should do to prepare or advice on what kind of diet/vitamins I should be on -- I would greatly appreciate it. Also looking for cycle buddies!!!
