I am 4 months post op, and pretty lucky in that things seem to have gone quite well so far. Something I've noticed in the last month or so though is how hungry I feel at night, and sometimes I feel like I really need to eat before I go to sleep, which is usually about 4 hours after my last meal. I often wake up feeling the same. Right now I am awake at midnight, not being able to sleep and and feeling like I need to eat. I don't think it is head hunger because I don't actually want to eat, it's more like a sensation of emptiness. Has anyone else had this? Am I actually hungry?! I am consuming around 500-900 calories a day. Pre op I was told I was prediabetes, so I wonder if my blood sugar might have something to do with it. Maybe I need to spread my meals out a bit more? Any ideas appreciated.
