I was put on ridiculously high amounts of bupernorphine (24mg, 16mg etc) for a period of 4 months over the summer for a codiene addiction. The clinic above are the people who prescribed it and now I am left with a much bigger problem (the subutex). I came off it for 6 weeks but had to go back on due to the EXTREME insomnia and lethargy. The insomnia being the most distressing.
