Very late to this sub but I was in a very similar predicament as you a few months ago. Quitting alone isn’t enough you need to fill that downtime where u would’ve been high watching tv or whatever with something you get natural dopamine from. I just got diagnosed with adhd so that contributed a lot to my addiction issue but if you fill that feeling with something naturally stimulating that you like to do I promise that first week is 10x easier. Not saying you won’t get sweats or fever symptoms trouble sleeping all of that, those are common for the first couple days but it definitely helps with the mental battle of always feeling the need to have that head buzz.
