Call doctor might be high bp :)
I was having those symptoms..my doc told me to go to walgreens and check my blood pressure and yes it was a little high so she told me to check it often and if I get a headache that wont go away or start to see spots to go to the hospital..call your doc and see what they reccomend..Good Luck and try to take it easy
to me it happenscif l don't take coffee in the morning. if you were used to it and suddenly stoped might be it..cos you say it hepls when you have an energy drink.
It's just an idea...but yes it's better to ask your doctor.
good luck
U need to call ur dr, could be high bp
