Headache on Optifast

I'm so glad to hear that I'm not the only one that is suffering with this terrible headache from the opti-fast. I'm only in day two so I'm hoping it gets better soon! My surgery is February 25 Toronto Western hospital.

Thanks for all the replies !! I didn't think I would feel this way, the headaches have been brutal ! I did take some Tylenol and it has helped . Tried the Broth and can't do it , and have been having some of the vegetables that I am allowed to have . I also find having the shakes 4 hrs hours apart helps ! Only 11 more days

Day 2 was the same for me. I was glad I started upon Opti on a Friday so I had the weekend to adjust before going back to work. A structured day really helps. Weekends are a bit tougher. By day 4 it's smooth sailing. Hang in there! It's so worth it!

Hi there. I scheduled to have my Reux n y surgery in February 25 and just started my opti fast. I am having my surgery at TWH as well. How was your experience? Who was your surgeon?

I am also on day two of opti fast and I have a massive headache too! I also have some nausea and fatigue. My nurse said it's withdrawl and Ketosis kicking in. She advised me to take extra strength Tylenol.
