Help getting some energy??

I have been going through a flare for the past year and each day that passes I seem to get worse. I have been hospitalized about a month ago, felt a little better afterwards but that was short lived. I am exhausted on a daily basis, and I think it's mainly due to me not eating enough. I am severely nauseous, the thought of most food makes me sick, I gag on everything. My dr just gave me zofran, I took it once this morning and didn't seem to help, as I gagged on my simple chicken and rice I was trying to have for lunch. I need some help getting my energy back! I have read how horrible protein shakes in the store are for you, wondering if there are any reputable ones anyone likes that doesn't have a bunch of junk in them? I'm not the healthiest eater, but I know there can be a lot of harmful ingredients in the drinks if your not careful.
Thanks!

Well, fatigue is a symptom of a uc flareup and until you heal your are going to be left with a lingering amount of fatigue no matter what you do. Certainly, if you are not eating well (and I know all too well how one can grow a distaste/disgust for food when flaring) then that is only exacerbating the fatigue, and likely your weight loss as well. I recommend eating lots of small, bland tasting meals, rather than eating big meals (as big meals can be uncomfortable afterwards). As far as protein shakes go, make you own if you are worried about the ingredients in the store bought ones. Peanut butter is a good source of protein and it can be mixed with yogurt, fruit, and other things you like in your blender. GMC and other body building stores have jars of concentrated protein powder you can mix in as well, but that stuff is super expensive (like $20 or more for a jug of it).
