Hey Benya, you are no alone in this:
I also quit caffeine -and alcohol and potato chips- for one year on 1. January.
Alcohol and potato chips won´t be much of a challenge for me, as I consumed those quite rarely anyway. To consume alcohol was just easier sometimes, than to always refuse to tave a drink…
And for potato chips I used to have an irritating blend of attraction and disgust at the same time, where the attraction sometimes just took over, till it wasn´t funny anymore.
However, to quit coffe felt and still feels hard, though.
I also had bad headaches for a couple of days since I quit caffeine, but not today anymore. So thumbs up!
That old habits are going to be forgotten, soon!
