Beatle-

I would do smoothies when you are having trouble. When my appetite is the pits, I would make a smoothie with plain high quality whey protein (whey protein BTW has been shown to possibly help neuropathy in I think chemo related neuropathies-so who knows whether or not it will help other forms-I drink it everyday, nut butter (almond), frozen berries, oats.

I also ate A LOT of avocado and high quality meats. There are great suggestions on here for good quality carbs-sweet potatoes are awesome! Chickpeas are a favorite of mine.
