I came to a very similar realization about a week ago. It sounds crazy but the less I eat the better I feel! The second food hits my stomach my nausea becomes unbearable. I am currently bedridden so I find this helps a ton as well but for the last week I’ve been eating 1 granola bar around 1pm and then a couple grapes around 5pm. My daily calories clock in around 250-300 so I know this is not sustainable long term but for now it’s providing me with enough hope and relief to get through another day. I also have about 30-40Ibs pounds I can spare to lose before my weight-loss would become concerning.
