Some people are dependent on chocolate or caffeine, others on alcohol. 

They may feel they derive some benefit from their habits, often finding them pleasurable indulgences, but there are also drawbacks.

I find myself ambivalent about the habit that I’ve embraced to address my disabling and deleterious medical problem of frequent palpitations.

I have tried medical management with beta blockers, but am limited by bradycardia induced at even the lowest doses.
