Dizzy and lack of stamina

i have been feeling dizzy lately (mostly when bending over or working) and I cannot keep up like I use to. having a hard time keeping up with kids when could before. 

is this normal?

Have you checked your blood pressure and blood sugar when this is happening?  It could be low blood pressure or sugar, or even a vitamin deficiency.  Definitely not unusual, but also something worth talking to your doctor about.

You may be getting dehydrated.  Please ensure you're getting enough liquids, because you will fall over and wake up later. Maybe. 

I agree, classic dehydration.  Get some Powerade Zero

Thank you! Powerade zero it is!
