FSG's are worth it. If you don't try, you won't know. I wished I had my favorite cereal, because the few we had availble got very boring over 90 days. Dark sheets are handy to section off your part of the tent and block out other people's lights. Especially from those people who come in at 2 in the morning.
Cookies are good, so are juice boxes.
Microwavable meals, such as ravioli with a bowl and can opener. When our hubby's were deployed to Kosovo this year we all met infront of our hanger to take polaroid pictures of each other. We stood infront of the big bambi bucket that has our company patch painted on it. Then we took the pictures and made cards out of them. Also we made a video, in that we released yellow ballons in support of our husbands.
