dehydration can occur easily with wds..especially if u had the runs like i did for 2 weeks...and vomiting will add to it...plus u feel like dog poo poo and dont drink ur water..dehydration can make u feel very tired and depressed..gatorade or water...a big coke bottle per day..fill it up and finish it..flush some toxins out as well
maybe you are not dehydrated but acidic instead.
