for me, mostly just poor sleep and focus/clarity. It creeps up on you slowly, til you realize youre just in a haze. Once you detox, life is much better.

And, yet, as an addict, i keep convincing myself that I can handle a little bit (like, 6-10 grams daily - which is nothing) and will re-addict myself every few months.

I should say that i have been actually handling 10 grams vastly better lately than i could even 6 grams a few years ago. Not sure what to attribute that to.

I really like coffee - i roast, grind and brew it at home. I should treat it as i do alcohol - only 1 drink, once in a while - but i'll probably remain like this for life...

hard to switch attention and context.

easy to fall into "first idea good idea trap".

lack of ability to work in priorities.

lack of ability achieve long term goals, as long as these are not just extensive usage of self.

procrastination.

all this before even health issues like blood pressure and sleep disruption.

if worth to drop at least once for half year - experience panic attacks may be - and get on track back with better control of addiction :)
