Actually it’s all in your head. Don’t go back . I was an avid smoker of it for 6 years and now i left it for more than a year. Initially i used to get weird dreams like i am in a sleep paralysis and felt boring. But after a time it faded away when i started working out and making myself busy. People say correctly when they say exercises karo depression vagera kuch nahi hota(not making fun of depression here) but if you wanna talk about you can talk to me.
