I went to the dr a while ago for a bad cough and he put me on antibiotis, i am done with those (have been done for about 1 week) but i think i have something else now. I dont have a cough:

I am dehydrated - my dad went to get me flavored water -because i havent been drinking water
My throat hurts
My sinuses hurt
My bones ache and my mucles hurt (possibly due to i am dehydration)
I am physically tired but not enough to sleep
My tongue is sore

The dr said if i am not better by tuesday to come in

How can i prevent my dehydration from getting worse
Last time i was sick i almost went to the hospital because of dehydration.
