I did the same thing. I was like "OMG what have I done!!??" It gets soo much easier the further out you get. It is rough being on all liquids, being nauseated, not getting enough fluids, etc... All of this passes though.
I'm almost 8 weeks out and it HAS gotten much better. I'm not going to lie and say I never want to eat more than I do now, but it's a head thing, I'm not really hungry for more than a few bites. Hang in there and if I can be any help, please feel free to ask. There are many others on here with a lot more knowledge than me, but I will help in any way I can. You can PM me anytime.
Good luck.
