Anyone else's appetite taking ages to return after sickness?

I had a sickness bug/flu thing last week. Didnt really eat for obvious reasons. However this week, despite the fact the flu has completely gone; I am really struggling to eat.

Before I had the bug I could do 2000kcal a day easy. I never reallg got much in the way of appetite supression from previous jabs. So far this week id be lucky to hit 800kcal a day. Just really struggling to have any appetite at all.

Anyone else finding it similar after having the flu this year?
