Best diet for Selective Intake Disorder and Iron/Vitamin D deficiency?

Try finding a nutritional/protein ready to drink shake that you like. Some of ‘em are nasty some of ‘em are alright. And then I buy a big box of them online. This really helped me when my adhd medication (vyvanse) took away my appetite. And I use it to help fill in the gaps in my nutrition. Also I’ll go through periods of food/meal hyperfixations. And I allow myself to basically eat those foods as often as I want to.
