I see... you don't seem to have a problem eating but more of how it makes you feel after you eat it. I have been in the hospital only twice for being underweight, but I do remember the doctor telling me about how the body reacts to the lack of food. He explained that we have hormones that work together, like two make the body react in a defensive way and two in a more emotional way. When the body defends against sickness the other two hormones can backdown or even shut off. In my case I was starving myself so my body stopped producing dopimiene and saratonenine.i dont make enough anymore. I am on Efflexor. I have tried others but this has been the best. I was also to stay away from protien or things that make me gassy, vegtables etc until i put atleast 5 lbs. i was in the hospital a week before i could even gain 3 lbs. it is the hardest thing to overcome, i am 45 and still struggle.
