Yep. I I had no appetite, severe insomnia, headaches and sweats for about 1-2 weeks when I came off of my heavy use, decade long pot habit. It felt like the flu. I'm glad I found r/leaves or I wouldn't have known those were withdrawal symptoms that would eventually go away!
I never plan to touch the stuff again.
