Dealing with appetite suppression side effect

After changing from 200mg SR to 450mg XL, my appetite is shot - which, honestly, I'm good with because another med I'm on (olanzapine) made me gain weight.

How do you deal with the lack of appetite when you're used to food being a huge focus in your life? It just feels strange to me to not think about (or eat) food all the time anymore.

Thanks!
