I haven't used Oxy in about 2 months. I was up to 60mg at a time and now I am back to 30mg. But I get a lot sicker now it seems. Gravol does the trick as far as mitigating the nausea, but it also makes me hella sleepy, like beyond just nodding. I asked the pharmacist, and he advised mixing the two would make me sleepy and so I shouldn't drive or do anything else that requires concentration, but he didn't say it was dangerous.
