I take it for Narcolepsy and it usually lasts about 4-5 hrs for me.
Depends on whether you mean how long is it effective, or how long until it can't be detected by a drug screen.
depends on tolerance , and what your diet consist of that day
Yes
Until you die. There is no time limit.
Nothing, large amounts is possible to show a false positive for PCP though (unlikely).
If 10mg methadone is an ok dose for you, then go for it my friend (:
Chewing a 10mg Oxycontin tablet will destroy the time release mechanism and you will get all 10mg at once. This is no the way the pill is supposed to be used and doing this is considered abuse and is illegal. From a health perspective, 10mg is not a high dose to receive at once, especially if you have a tolerance. With that said, chewing the 10mg tablet will provide faster acting and stronger pain relief, but will not last as long as taking the pill whole. IF you need fast pain relief, talk to your doctor, he will most likely prescribe you emergency pain tablets for breakthrough. I have these, I'm on 80mg Oxycontin tabs, one a day, and I also have 15mg instant release roxicodone tabs for breakthrough pain.
lolwut?
Within 15 minutes to half an hour
No. the half life of Valium is 3-5 days at most.
The usual dosage of Ritalin for an adult is 10 - 30 mg per day, but can be as high as 60 mg per day. The effects of this drug should last 8 - 12 hours, but may not be as pronounced during the last hour or two.
my doctor says cyclobenzaprine 10mg is stronger
