I have now been able to hold my breath as I swim, just as I did when I was a lifeguard.
I've tried e-cigs in the past, but the batteries were way too week, and filling up the those old school 510's were a pain in the ass. Now that the tech has caught up, and I for one am stoked.
It's been 2 months now since I've had an analog, and I for one feel better. I haven't gained any weight, I wake up not so grouchy and lowered my nicotine level. These things rock, I'm just glad the tech caught up.
