Lost Appetite

Well, night shifts have done it to me again. I have completely lost my appetite. While I was off for my 12 days I ate healthily and had 2-3 regular meals each day. I felt great.
Now that I have worked one set of days and am in the middle of a set of nights my appetite has gone completely. I don't feel like eating, but I force myself to do so.
On day shifts I have 1 hour- and 2 half-hour long breaks, while on nights I have 4 half-hour breaks (along with numerous other half-hours when I have nothing to do). I fit my eating into these breaks, but it is almost always forced. I feel like I have to eat during these times as otherwise I may feel hungry when I am unable to eat. Sometimes I eat during these breaks just because it is something to do (as there is nothing else to do, whether I am on my break or not!).

I do not trust the hygiene of the fridge at work, or the trustworthiness of my colleagues or others who have access to the area, to leave any food there so I have to take food in that will not spoil while it is in my locker. This leave just junk food really. Sandwiches, crisps, biscuits, sweets etc.
I don't take fruit in because I am incredibly fussy about what I like and how I like it (i.e. banana's have to be the right temperature and softness before I will even entertain eating them. I can't eat them the same day as I buy them from the shop! Weird I know, but I can't help it). During the day I could get freshly cooked food that is relatively healthy from various shop hereabouts (at least on weekdays), but it is all so expensive, being the city I guess they expect everyone to be on great wages.
Then, when I get home from work I am too tired to cook anything (from lack of stimuli, not hard work). So I end up eating junk there too (microwave rice, pizzas, etc). This morning when I got in from work I forced myself to eat some cereal, but I really did not want it. I also cooked some chicken Kiev with microwave rice for a late lunch this afternoon, but wasn't really hungry when I ate it.
Now my stomach feels bloated from all the crap that I am eating and I won't even mention what is happening in the toilet department!!!! (Sorry).
I am really going to have to come up with alternate foods to bring into work if I am going to be forced to continue to work here. I just wish I wasn't so fussy with my food.

I need to stop working nights. It's bad for me.
