I just quit a couple days ago (have been vaping weed out of a Volcano everyday, several times a day for 3-4 years) I've been getting really bad sporadic horrible diarrhea from withdrawals. I can't eat (kind of hungry, but absolutely no appetite) and during the daytime my stomach feels uneasy.
I didn't just quit cold turkey. I slowed down on the vaping (a couple weeks back), and ran out of my higher quality weed. I switched to some lower quality weed and only smoked out of a bowl in the morning and at night. 3-4 days ago I stopped smoking altogether. I've stopped in the past and I was kind of worried I wouldn't be able to sleep, But that doesn't seem to be the issue this time. I just keep getting the squirt poops.
Hope my reply helps another worried quitter like myself, You're not alone.
