Snow

I'm not banded yet, but I'm doing all my pre-op work--getting my bloodwork done, seeing the specialists, all that.
I had a fasting glucose test this morning, and my mom wasn't available until noon to watch my daughter, so I woke up and had to go until noon without eating. It's probably the fat girl in me, but when someone tells me I CAN'T eat, I get that much more hungry. By the time I dropped my daughter off, got my bloodwork done, ran an errand to the bank, and got back to my mom's, I was a raving b***h. I'm usually an obnoxiously cheerful, upbeat person, but feeling hangry isn't a new thing--I always get a bit short when I'm hungry. But this was like hunger on steroids.
I was grumpy and short tempered, and probably acted like I had a giant stick up my arse. My daughter was fussy (she's 9 months) and I caught myself wanting to yell at her for crying. Ridiculous! My mom was obviously uncomfortable with me and my foul mood, and I got home and realized I'll probably feel like this a lot during that Bandster Hell period--before my first fill. I'll likely be tired and sore and hungry, and may have difficulties actually eating. If that's the case, I don't want to turn into a raging cow and alienate everyone who's going to be around to help me-- not to mention my kids.
Did / Do any of you go through anything similar? Any words of encouragement or advice?
