I've had a few of these over the years, Red Bull, Lucozade and other supermarket variations. As I was in the Shell garage on Thursday night filling up for the Courtenay visit, I noticed a special offer on Relentless, a large can 500ml energy drink. It was 2 cans for £2.20. Never tried it before so I bought some.
I set off at 3.40am on the motorway and after about 20 minutes of driving I thought that i'd better open a can as I was dozing a bit. I drank the can over a period of about 15 minutes and it wasn't long before I was wide awake. After about an hour I started to crash out hard. My eyes were rolling and my eyelids were trying to close. So I opened the second can and bang I was wide awake again. I stayed like this unti lthe sun came up and I arrived just outside of Norwich. I then felt overwhelmingly tired again. The fact that it was light and I was in traffic kept me awake but all that I wanted to do was shut my eyes.
Has anyone else experienced this up and down whilst drinking these sort of energy drinks?
(BTW, the coffe at Courtenay is awesome. I drank about 5 cups during the day and by the time I left my heart was racing and I was shaking!! Woohoo!)
