As a sensible adult I should tell you to forget about it. Driving while tired is too dangerous whatever you have taken to help. What you need is sleep.



But, as you are going to ignore the first part;

Coffee.

Seriously, a well brewed filter coffee has about the same amount of caffeine as 3 cans of red bull (and usually at half the price). Just take plenty of breaks as you drive and top up with coffee and sugary snacks and you should be fine. and that will be much cheaper than and of those energy drinks out there.Whats the best over the counter supplement or energy drink or shot, enhancer out there?
I like to drink FRS. It gives me a really good boost without the nasty crash of most regular energy drinks. I also dont like those little shots. Kinda feels like drinking chemicals. They have FRS in some Grocery stores.Whats the best over the counter supplement or energy drink or shot, enhancer out there?
