Sorry for the overload Irishguy..
But these things are important and surgeons generally do not want to share...they're so busy cutting.
Your symptoms sound like dehydration to me or loss of potassium which is Hypokalemia and you really should report it to your doctor..you seem young and fit and probably rebound quickly but you don't want to mess with it either. And loss of fluids on a regular basis can cause it.
Symptoms of Hypokalemia:
Hypokalemia ranges from very ornate to severe level. A person suffering from simple/harmless/primary staged hypokalemia may experience no symptoms at all, but general symptoms of hypokalemia are:
Fatigue
Patient may experience problems such as Myalgia and muscular weakness
Patient may experience hyponatremia and also may experience confused i.e. anxiety.
Acme problem
Skin related problems such as blistering, skin eruptions, dryness of skin etc.
Temporary memory loss or problems such as weak memory etc.
Patient is prone to heart related problems, such as heart deterioration.
Digestive system also may get affected due to potassium deficiency leading to hypertension, improper sleep, nervous system deterioration, depression, constipation etc.
In some cases patient may experience ringing/noise in ear.
So keep the Gatoraid nearby.. and do let your doc know you are experiencing this........sorry for adding to your misery.......Pat:S
