I fall asleep with it in my hand, and thankfully wake up with it still in my hand (now I know that when I sleep I sleep like a log, ha ha!).
By the grace of God, my smashed and black-out episodes are 7 yrs behind me. I know if I was still doing it, there would be a lot of lost/broken batteries scattered about the house, provided I could even find themLMAO that is hilarious! One morning I couldn't find mine, and I had a panic attack...I had gotten SMASHED the night before and blacked out...I found it under the couch, and the battery was broken. It still worked, but the plastic thing on the end was knocked off, exposing the LED, so when I took a puff it looked like I was sucking on a flashlight.
i vape before sleeping then again as soon as i wake in the morning
Knowing how any battery can go wonkers at any time, I always untwist my atty, and set it on the table beside me where I sleep.
