I'm trying so hard to get my GM to send me home so I can go into L&D. I've been at work since 4:30am and we have no air. I've already drank 64oz of water and I feel a little dizzy, hungry, have a headache and feel sick to my stomach. Normally I can tackle feeling like this but today I'm so out of focus I haven't even been counting his kicks or movements. The only way they'll probably send me home is I pass out. I hope it don't come to that.
