I had UC so I know first hand what you're going through. Instead of vomiting I had diarhhea which landed me in the hospital with dehydration. The gastos are useless btw, but I guess you already know that.
And I see you are starving as well, just like I was. Yes, you are eating, but you are not absorbing any nutrients from the food!! This can be for many reasons, but I hope you are not using the microwave, and a parasite cleanse can help very much here.
You were smart to get off the drugs, they will only make you worse. I know 2 other guys with UC who didn't, and they can no longer work and are crapping out of a tube through their chest, and you don't want that.
The best thing I can tell you is to go fruitarian for 3 months. It's not a long term diet, it's a cleansing diet. MH's orange fast also works great, same principle. Download BOOK I from MH and follow it!
To be fruitarian, pick a single fruit that you like and eat it as a meal and eat as much as you want. For example, eat apples for breakfast, plums for lunch, oranges for dinner. Start slow, try only 1 fruit meal every 3 days and include more fruit meals from there. The detox can be strong, so that's why you want to start slow.
You can see everything I did below. It's kind of long.
There is a lot to know, but the main thing is to get you out of "crisis" mode right now. Reading Book I and following it, you should feel major improvement in a week or two.
As for the chinese medecine, I'd stop doing it, $45 a week is an insane amount of money for only "kind of" helping. I too took chinese medecine and it didn't help at all. Acupuncture also didn't help because I didn't have an energy in my body to redirect! Anyway, do as you please, I just wouldn't waste my time and money with it.
