I am 3 years sober off a benzo, coke, opiate addiction.. Smoke weed once in a while and im prescribed my xanax still and can take them periodically w.o slipping, but now im obsessed w.coffee, is that a thing that happens?

Big hug! Congratulations on the milestone, always pat yourself on the back soundly for these events,  you deserve it! I am a recovering alcoholic, I count years, too. Coffee is absolutely addictive, and you can get headaches if you drink a lot then suddenly stop. Usually it's us that's the problem, not the substance, though. You know that. Protect yourself from yourself!

Hugs, Devlyn

I have heard  that it isn't unusual to switch one addiction for another.  Maybe you just have to go for the healthiest addiction option.

It is absolutely a thing that happens. Coffee was really my first addiction.

I am an addict, you give me something that changes how I feel even if it is just a little bit, I eventually will start to abuse it.

I haven't had a drink in three and a half years or a cig in almost two. Every time I quit one thing another gets worse. I have been going in order of most to least harmful. First booze and occasional pills went away only to be filled by soda and chain smoking. Quit the cigs and then got bad into pot. Medical necessity forced me to quit caffeine and sugar for a bit last year so I got sucked in to my original nullifier...TV. I know I can't quit everything so I'm working on my self worth instead, that has helped me learn to moderate my intake of these lesser evils. Booze and cigs are addictive dopamine receptor flooding chemical addictions so they are out for good. So yeah, one for another is often how it goes. A guy in my sobriety support group chastized me for smoking pot after three months without booze, just cigs and caffeine, the two drugs he says he'll never quit.

And congrats on kicking opiates, that takes major strength!

Caffeine is the worlds most commonly used addictive CNS stimulant, followed closely by nicotine. Caffeine concentrations in a single cup of coffee would not be addictive and can actually be good for your body. Overdosing on caffeine can cause hallucinations, diarrhea, heart palpitations, or heart attack.

The average cup of coffee contains about 50-60mg of caffeine, anything beyond 800mg would produce OD effects.

You are probably trying to use coffee to replace your opiate habit. Which isnt neccesarily a bad thing.
