I do the same as Kellgee, I have small meals (or whatever I can manage) every 2 to 3 hours. Usually this consists of 1 medium sized apple, a salad, or something along those lines. Sometimes it is just a hand full of nuts. While my mind says I'm not hungry I still know that I need to eat something to fuel my body and metabolism. I am starting to notice though that my appietite is coming back in the evenings. I've actually started eating later at night because that is when I can eat something subtaintual enough. Give your body some time to adjust to the med.
I also agree that you need to start incorporting exercise into your day. After I do an intense 55 minute circuit I feel like I'm starving. Up to an hour after your workout is a great time eat, especially carbs.
I would start exercising and see how that changes your emotional state and appietite. That may just be the key for you. It really helps me on a daily basis.
Hope this helps!
