I go through ups and downs too, still, 15 months into eating restorative amounts…my appetite began around 2000 cals, and has fluctuated anywhere from 2300-4500 daily. Usually there are weeks I eat more and weeks I eat less. Right now I’m around 2800/day. Often I find I am more fatigued when I eat more, simply because I still have huge adrenaline shifts which send me into wired mode and crash after I replenish my stores.
Usually when I’m nauseated I eat pretzels. The salt and simple carbs open up my appetite and give me good energy! Salt is very helpful for my nausea.
