kinda of all in the title. whoever has any experience with this please post. I take opiates like once a week as kind of a celebration/day off. been doing this for years. the only thing I have available is oxy. 5 days ago I took 50mg orally after taking gabapentin the night before and it felt like taking 20. about 5 days before this I took 30mg of hydro and I was nodding for 4 hours. this is the only variable I see. could gabapentins effects on metabolizing oxycodone into oxymorphone really be this severe? btw, I took 30mg and disappointed took my other 20 about 1.75 hrs later.
