Those drugs aren't better, in my experience, as a chronic pain patient. Morphine is way less addictive, longer lasting, with fewer side effects. Not to mention, it's natural, one of the main alkaloids from poppy. Now, I'm not a dolt who thinks natural is better. However, most synthetics are strictly worse from a therapeutic standpoint. This view is based on my experience with them and from my discussions with other patients. From what I understand, the synthetics are pushed on patients for incentives. I had to pretty much demand morphine instead of oxy. Thanks Sackler family!
Morphine XR (MSCont) is also pushed instead of normal morphine, again, I think for similar reasons. Although on the surface, it might seem like an XR would be helpful. Instead it just causes more constipation and doesn't give a great absorption profile.
Morphine IR 30mgs taken throughout the day pretty much vaniquished my pain. These days though, I use Kratom, Mitragyna Speciosa. It's as effective as morphine with less side effects. I also try to work out every day. Having strong muscles in the painful areas seems to help with the pain, either due to increased blood flow or perhaps for other reasons.
Nucynta (Tapentadol) was the most effective synthetic opioid I ever used but without insurance it cost me $3000 a bottle. Kratom is cheap as dirt even without insurance. $70-80 buys 1 kilo / 2.5 pounds of the ground up leaf. I have enough kratom in my cabinets to last a covid apocalypse.
You can get lab tested Kratom that is cGMP certified these days. I have nothing to gain by providing this information, just happy I found a pain reliever that is sustainable and doesn't require talking to a doctor playing a drug pusher every month.
Lots of people have had bad experiences with kratom giving them headaches/nausea. This is largely due to poor quality kratom from head-shops and gas stations or from consuming excessive doses. Never buy Kratom that isn't lab tested with GC/MS. And don't take too much of any opioid unless you want motion sickness.
