I went back to work after my 1 month post-op follow-up. Luckily I work at a small shop where the employees all care about each other, so explaining my limitations was easy, but definitely go in to your supervisor and explain your medically necessary breaks to sip/eat throughout your workday. It is important that they clear you upfront for this. I still forget to stop and drink often enough to fight symptoms of dehydration off. You have to be able to focus on this or you can get lightheaded or shaky at work. Physical exertion is still going to drain you quicker because of the reduced calories, sometimes surprisingly so, just listen to your body's signals and communicate clearly with your supervisor/coworkers how you feel and why so they can help or at least understand the new you.
