In my packet of info from the hospital it actually says "you may feel you are on an emotional Rollercoaster"
It will get better, right now....don't look any farther then today. One day at a time. If you actually feel hungry it may be acid in the stomach, or head hunger. We go from eating whatever whenever to not eating at all. It's really hard, but let me tell you....it's worth it. You are going to be amazed at how good your going to feel. It was my 3rd week out when I noticed I felt pretty darn good. Pain subsided, started a little excercise. Then I hit the dreaded 3 week stall and got really down on myself. With the words of others I realised this was just time my body needed to play catch up. I'm 20 weeks out and down 80pounds. I feel like a new person, and soon you will too.
Just get through one day at a time (it's all that wacky stuff going on inside our bodies that makes up weepy)
