Food rejection?

Hello! So I've been on biologics for a while now. I had to change from my initial biologic as I had acute Liver failure happen from the first one. Anywho I'm now on Stelara, and I've noticed since starting them last October that everytime after my Infusion I have food rejection. I'm starving and hungry but the minute I eat or drink something, my body just doesn't want it, I get super nauseous and wanna puke. It's an almost immediate nope even though everything in me is like yes food! Does this happen to anyone else? Is this normal!? I've lost alot of weight in the last year as well, and my appetite definitely has gotten less but is this normal? Please help.
