Ok, feeling relieved. It really is a very overwhelming feeling, especially when it's every single time I'm standing for more then a minute or so. I'll try taking some snacks in my handbag. I have started taking bottles of water with me, but it doesn't help much. It's all for a good cause, so like i said, as long as the baby is ok, it's all I care about!
I have one more question, so I might start another thread...
