Or if you don't want to talk to the doc, and you honestly think you have a problem, try using half for a while and then one quarter, weaning yourself off but Duck is right (as he almost invariably is), you probably don't have a problem if 20 mg still has an effect on you and you never upped your dosage in order to compensate. I believe I recall that a threshold dosage for addiction (a reaction occuring if one stops taking a particular medication - a physical reaction) was in the neighborhood of 6 - 8 mg of xanax per day for an extended period. Now temazapan is not xanax and xanax is an order of magnitude "stronger" than temazapam but the ordinarly dose of xanax is somwhere between .25 and 1 mg so you can compare.
This is a marijuana site, when I have problems sleeping and I just can't work out the details I get the most couchlock smoke I can find and take a hit JUST before I go to bed. For me it is a sort of crapshoot, as if it works, it works well and I sleep great, If it doesnt (like now with this stupid fentanyl withdrawal) then I am stuck being high for the next 3 or 4 hours and tired on top of it. Most folks here don't see a problem with that at all - you may not either, but I don't really like a marijuana high except in very specific situations. so for me, if didn't manage to sleep, I will just have to endure endless circles of thoughts or hearing fragments of songs over and over and over and over again, or contemplating the fact that I have not done anything with my life or how I should have been more loving toward my mother or how I simply MUST fix that drawer in the kitchen that sticks.
Like that.
