Bunavail
"Bunavail work great for detox and keeping away from opiates but there is one major draw back and that's getting the film not to roll back on itself in which you lose probably 1/4 of absorption not going into you cheek and instead it can sit in your mouth your saliva hoping to get it distributed elsewhere like the underneath of tongue. I have tried bending the corners to  prevent the rolling which helps a little but the film still wants to roll, bend corners 90° for best results. Not supposed to cut the films but manys docs say to do it which is fine because the bup and nalox is equal distributed, I called bunavail to check. But when you cut the films seems to be worse on rolling up because less surface that the film has to stick to your cheek"
