Good info Speed King. Something I can't stress emphatically enough though, withdrawals from taking subutex long term, especially though non recommended ROA's is BRUTAL. Not I severity but in duration. I've tried coming off subs several times One tapered down to literally .5 of a mg daily and was kicking all night and taking hot showers for three and 1/2 weeks before i finally caved and got refilled my script. Ive read horror stories of people feeling like shit For months. If u decide to get on tex... Take it short term and ONLY sublingually in recommended doses
