Anyone currently using optifast? I am doing a week of Slimfast while I wait to get my assessment to be on optifast. Thought this would give me an idea of if I can tolerate the shakes for meals. I need to lose 75 to 100....I'm on metformin to keep my a1c down. Also on thyroid meds. I'm on other meds for depression and anxiety, had heart surgery in January for genetic issue, breast cancer survivor, have chronic back leg knee pain

....I'm a mess. Im a chronic late night overe eater.....I'm 48 and want to be around during to enjoy my future grandkids so I need a huge change.
