Can someone provide more information on the 1-month recovery from caffeine induced anxiety? In my experience and from what I've read online, caffeine withdrawal typically lasts 1 or 2 weeks. I recently quit drinking coffee hoping I could stop grinding my teeth in the night. It hasn't helped yet, but I quit only about 3 weeks ago. An aside, grinding your teeth in the night is very problematic because it's not something you can directly resolve unless you get a mouth guard. Trying to pinpoint stressors in my life has been an arduous process.
