Given the choice between going through hydro or tramadol withdrawal, I would take the hydro withdrawal in a heart beat, the lesser of two evils. I find I build up a tolerance to hydro too quickly, much more quickly than with tramadol. Probably depends on the dosage and different for every one. My worst experience was coming off of dhc, back when libsol was selling the 120mg and 60mg tablets dirt cheap. A week of pure hell after taking them for 6 months after a car accident.
