Yeah, you might wanna drink your meals until you're well. Well, okay, not wanna, but it's the path of least resistance. The crap that's premixed at the grocery store in the frozen aisle is essentially a milkshake so not so healthy long-term, but it's delicious and you won't die immediately on it. If you go that route for a few days, gradually introduce solid food back into your diet. Your body can very quickly forget how to digest something if your GI tract is already weakened (as yours certainly is right now).
I hope you have someone to take care of you. A flat mate or somethin'.
