Wasting valuable eating window time

If this is a little long I apologize. I just recently started a clinical rotation in the Operating Room. I have to go to breaks with my preceptor. Break times vary from day to day, based on the surgeries so it is hard to get over 14 hours of fasting. My first break is at 9ish usually and then my 8 hour fasting window is ticking down and over by 5, just in time for me to usually eat dinner. I don't want to skip any opportunities for food at the hospital, you never know when your next break is, or if you even get one. I suppose my question is this, while i was planning on eventually going up to a 20:4, is that something i should be trying now? Just go big for the 3 days I'm there, and then the days i have more control change the window? I just wanted some opinions or what someone with experience recommendeds. via /r/intermittentfasting https://ift.tt/3jq3r2T https://ift.tt/eA8V8J
