I can def say that my diet is a lot different since starting Lexapro. My Dr. said that since starting it, I've developed ARFID, due to my fear of getting sick from eating (because Lexapro used to make me feel sick). Try not to force yourself to eat because your body's gonna hate you for it. If it's legal in your state, you could try medicinal marijuana. If not, there are a few medications that can counteract that side effect. If you're not favoring the idea of taking more meds, you could try building up your meals slowly over time. It's what I'm trying rn, and it's really hard, but it makes a hell of a difference.
