Hello, this is a never ending guessing game. I had mine done two years ago. I stated out writing everything down, so I would know when I could eat, what I could eat, what would make me sick ect...All I know is, I don't get hungry in the mornings, I don't eat anything during the day (usually). If I do I usually throw up. There are some things I can eat just fine and other times the same thing will make me throw up. I have found that if my husband wants to go to dinner, we will go a couple days, or the day before if I calculate right, before my period starts. For some reason right before my period I can eat more than I should be able to, but if I were to try and eat the same amount after my period starts, forget it. I usually have to make myself throw up, I will be eating, slow and small bites, and I'll feel like it's in my throat and I get an instant headache, after I throw up it goes away. My frustration will this whole thing is it's been two years and I have only lost 65lbs. Although I don't exercise like I should and since I don't get hungry during the day, I always eat at night, and if it's been while since I have actually been able to eat anything good without throwing up, I find myself eating all the wrong things because I can, like chips and dip, popcorn or candy. I was hoping to to get on this site and find like buddy support. Well good look with your success.
