Oh I know it to well too!: but I eat something called “Skyr” an islandic form of youghurt, that is packed with protein, and therefore takes care of the need for nourishment for a long time :-). I remember my ADHD medication, it’s besidde the refrigerator (skyr) and cofee = nuding! Yeah! And also the ADHD medication I take, supresses the hunger feeling. So not all is hyperfocus for me. I think it’s the intense concentration + the interest in what I’m doing, because if I’m not that interested, I feel my need for food a lot.
NB I’m sorry for spelling errors ao, beare with me, I’m from Denmark ☺
