I was driving to work at 7am,  and felt like I was dosing off.  Slept great, that night.  I got to my job 40 minutes later and started to feel dizzy and light headed and weak,tired.  I dont drink but I do smoke about 10-15 digs a day.  I gave up fast food about 6 weeks ago and I have a leafy green with fruit nutri blast every morning for about 2 weeks now.  Thats the only thing that Ihave changed,  wondering if I put my body through shock, not eating garbage any more.  I am on meds for blood pressure is fine.  Weather is very hot and humid but dont believe it is heat exhaustion.  Drink about 40-52 ozs water per day.  Trying to use process of elimination before running to doctor, dont have insurance.any advice,  Valeri,
