I am having my braces off tomorrow, what to expect?

Life after braces. Is great. The dentist/orthodontist will remove all brackets, clean all the glue off your teeth, and take an impression for your new retainer. Many orthodontists now recommend wearing retainers for many years, and sometimes forever, to prevent teeth from slowly shifting out of place to a previous position. Good luck.
Hooray!!! The end of the corrective process and the beginning of the rest of your life with a super smile. Off is easier than on. Some very bearable pressure when braces removed. Orthodontist will then remove residual bonding material, polish your teeth, and will take impressions for retainers! Prepare for much joy! Congratulations.
