I'm on the same medicine, but coffee is significantly easier to quit for me. If I take a single day off meds, then I feel it, and that feeling compounds for about a week. The withdrawals, in my opinion, while not particularly painful in a physical sense, and still fucking brutal.

I'm on a child's dosage too, which is crazy. Yeah yeah, I know everyone is different and all that, but I can see why this drug is a Schedule II Controlled Substance in the US. I am not sure how addicting it is from a psychological point of view at therapeutic dosages, but it's damn easy to build a dependence in my experience.
