I have some Prednisone I can use at the same time as the MJ to enable me to go cold turkey on the Hydrocodone/Norco/Oxycodone type stuff.
You don't want to do that Mark. If you've been on it and are dependant on it, wihtdrawals are NOT going to make you feel better. Don't take my word for it, ask your doc who is managing your pain. Are you seeing a pain specialist?
Also, I think you are going to be very disappointed about how much pain the weed is going to relieve. I am not a pain specialist, but I seriously doubt marijuana is going to take care of your pain. I think it's worth a shot, and you may see some benefit overall, but pain relief is not likely to be a big part of that.
