How Long Does A Red Bull Take To Kick And How Long Does It Last?

For me, it didn't take too long to kick in. After about 2 to 2 1/2 hours I fell and I fell hard.

I found another drink that lasts all day for me. It is a powder that you mix with water. It is called Advanced Cell Therapy, or ACT. I take 1/2 of a package in the morning with 8 ounces of water and 1/2 of a package in the afternoon with 8 ounces of water and it lasts me all day. Plus, it only has 5 carbs and 22 calories and it only costs $1 per package.

Both would depend on YOUR metabolism.

For me personally it doesn't work at all and gives me a horrible stomach ache. I like it better when mixed in a cocktail.

Yuck.. Red bull is mostly made up of sugars and sweetners therefor it gives you energy.. if you burn it off it wont last very long, if you dont burn it off it will turn to fat =)
They take only a few minutes to kick in and they last for a few hours, however, you're only suppose to drink one a day as they are loaded with caffine, I used to buy them in packs of four and drink them all in one go, one after the other, and I'd be bouncing off the walls do things by "impulse" and unable to settle down for hours at a time, thankfully though, I stopped doing this, it eventually got to me, and I had to settle down and stop being seriously wired!
