"i have been prescribed 8mg sub. buprenorphine. one a day for over 2 years. i cut one into for 4 to 8 pieces and take tiny piece a once or twice daily. my pain is manageable and a 30 tab prescription lasts for 2 to 3 months. i no longer depend on opiates and no longer wake up in morning with body cramps and pain in my entire body from opiates wearing off. my pain isn&#039;t as intense. when i was taking opiates my pain got worse by the day. my tolerance to them grew by month. i don&#039;t know why this drug isn&#039;t used more in the us. it took me 3 days to make the change from daily high doses of opiates to buprenorphine. i did take most of a full tab those 3 mornings. if you really want to stop opiates and take very little medication i recommend."
