I did this same shit last year. They had this bed that was only 12 minutes, but it was $30 for one fucking tan! I'm use to going in the cheap ass beds at my gym for 20 minutes. So I was always wondering about it, til one day I decided to go ahead and give it a shot. Big mistake. I was so damn red, it's just embarassing when you do that too. Now I've learned to just take it slow, and if I'm ever in doubt, go less time not more, that way you can go again in the next day or two.LOL
