A few weeks back I had the pleasure of my first opiate experience. I took just 5 mg oxycodone, but being completely opiate-naive I did feel the effects, though I found them a bit subtle. But, also in a way they weren't subtle. It is hard to explain. Anyhow, I have access to 4 more 5 mg pills. What would be the best to do with these? Should I use them seperately for 4 5 mg doses? Is it that opiates at certain doses are subtle, and their effects have to be learned to be appreciated? Should I take 10 mg instead? Other than the 5 mg a few weeks ago, I am completely opiate-naive. I have extensive knowledge about opiates, but can't figure out how much I should take the next time. I am afraid to waste these pills, as they won't be coming around again. Please share your thoughts on the matter. Thank you. By the way I weigh 140 lbs.
