I used to like eating eggs every morning and after starting meds I really quickly lost interest and switched to eating yogurt with flax seeds, a bit of maple syrup, and some oats or all-bran buds. It's probably a healthier breakfast. I can't stand mixed greens lately, but I think that's just the season.
I didn't really notice any other preference changes.
It mostly just feels like I have more energy and I spend more time actually doing things. A lot of stuff like listening to music felt way better and I used to have to be drunk to feel that way.
