Small Meals vs. Grazing

Before and after surgery I eat/ate 3 meals a day with an occasional snack after dinner. My biggest reason, other than that is the way my surgical team told me to do it, is because if I eat more often, there's a lot of missed times to be drinking water (since we have to wait at least 30 minutes before and after). I end up eating probably every 5 hours and I haven't had any problems with it.
