Apparently, my local public hospital is struggling with an influx of flu patients. I'm not surprised as I found myself on the verge of severe dehydration last night. Thankfully, with sugary ice poles and electrolytes I was able to get my fluids up. I'm still a little dehydrated today but I think I will be fine. This is a nasty strain of the flu, my knees have been hurting like I was hit by a baseball for days.
I was so tired last night I almost missed that I was as sick as I was. It was noticing that I was irritable that made me check the symptoms of dehydration. That, and I was so very fatigued. I thought I should check, and then I got on it, and my fatigue has improved. Mind you, over ten hours of sleep last night!
This is a good guide to dehydration, written by Medical Doctors (hence the md in the title):
If in doubt, call your local emergency department for medical advice.
