i have been up for 24 hours. i had some oxycontin about 4 hours ago for the first time. snorted some. and ate a tiny bit with the extended release coating on it. i have now taken my usual sleeping pills and have found that i cant sleep!! i should be barely able to keep my eyes open on a normal day after being awake for so long. has anyone else experienced this? also do you have any suggestions for remedies?
