No problem, I'm just sorry I can't help more-- it pains me to see people suffering.
If your stomach is sensitive some other things you can try are bananas, applesauce, toast, and crackers (whole wheat is the best for fiber, ie Triscuits, Wheat Thins). Popcorn (plain) is pretty good too, and is high in fiber for the calorie content. Maybe orange juice if you're not citrus-sensitive? This is America, land of obesity, should be something you can eat

Dark chocolate maybe? It tastes good, effects the mood positively, and has a lot of magnesium and antioxidants. (man, I'm totally craving fruit juice after typing this)
If you're only getting soup that's pretty rough and you might even be feeling some ill effects from malnutrition. Even if you're not hungry you might try eating more "light" things so that you're getting enough calories and nutrients. Also, there are many types of soup out there, some are more healthy and nutritious than others, if you can tolerate it look for one with meat, veggies, and whole grains, that should give you some good protein and fiber.
Coffee isn't damaging and I wouldn't worry about it too much, but caffeine's half-life is 4 hours so if you switch to decaff or fruit juice or something after 6pm sleeping should be easier for you. It's good for improving your energy and mood through the day though.
And finally, if you're willing to take supplements... a multivitamin, fish oil (omega-3 fatty acids), and maybe calcium/magnesium supplements in addition to those can help you get the nutrition your body needs. There's no RDA for omega-3s but there probably should be.
I hope you're at least getting a non-starvation amount of calories per day, if you drop too low your body doesn't have enough sugar and goes into ketosis, where ketones are generated. These are acidic and can worsen stomach problems. You will also feel fatigued and tired in ketosis. You need at least 400 calories (100 grams) of carbohydrates to maintain your liver glycogen stores each day, and some extra for activities etc (you burn it faster with stimulants too), so make sure to suck down that sugar. Also try to get 60 grams of protein per day and 200 fat calories or so, that will keep your body out of muscle cannibalization and starvation mode.
Sorry, enough rambling about nutrition... I just hope you start feeling better soon, and make sure to eat what your body needs even if you aren't hungry, nicotine is very good at masking your appetite, so you might not be able to rely on hunger alone with it in your system. I don't know what food you can safely put down with your stomach the way it is but try things in small quantities and see how they do. Might want to be careful with prunes

Good luck man... you can get through this!
