I just wanted to post to goodness for now. You must be careful reducing your meds and do one drug at a time. If you are not happy with doing with the guidance of your pain nurses/docs (and I fully understand why) and want to do it yourself, your need to be really really slow at reducing. It's called Titrating downwards (and is often done upwards for some of the meds you are on). Meds such as Gabapentin, Amytriptiline for example have to be done slowly, and you WILL get withdrawal for a little while. They are not just painkillers, they affect how your brain works. They increase seratonin, they decrease something else, they make you sleepy/drowsy, and they Get Into Your System. You have been taking them for a month now, at reasonable doses. If you reduce too quickly you will a) make yourself feel dreadful, b) suffer from sleep issues for a while and c) put yourself at risk of having a seizure as these meds affect all sorts of chemicals in the brain.
I will give you an example of how I titrated upwards on Gabapentin and Amytriptiline so you can see the dose differences.
Gabapentin - 100mg/150mg. Stopped there as I couldn't deal with the side effects. Some people go up to 1000s.
Amytriptiline - 20mg/50mg. Stopped there as I couldn't go any higher (possibly went to 75mg, not sure if that was this or Pregabalin, think it was the second).
With both of those I went upwards two weeks at a time. And was meant to come down 2 weeks each titration. I stopped gabapentin without titrating downwards but only just got to second increase and it was the first one I had taken of its kind so wasn't prepared to give it the 5 weeks I was told.
With amytriptyline I stopped it cold turkey. I was Really Fucking Sick. I didn't put it down to that at the time, it took a few days of realising my sickness was not going away before it twigged that I had stopped it outright.
If you are cutting down from 300mg -200mg that is probably a reasonable cut, maybe a little high, although 50mg is much slower and better for you side effects wise, however, one week in is not enough time ti get used to it so you are in effect cutting out 200mg from your body, that is too quick. And, if you are adding oxycodone to the mix of reduction, that will have it's own withdrawal side effects. This is NOT the same as addiction, it is physical affects as the drugs have different half lives. You may find the final withdrawal of these drugs quite hard for a week depending on the half life, but it's purely physical. So you MUST pace yourself.
There is no rush. losty is completely right. This is the new improve You and there is no rush to get there and risk it taking twice as long. You have HAD to have these meds or else be in huge amounts of pain, especially if the level of nerve damage was unknown at the time. You will be free of them soon, just not as soon as you want.
I do understand. One of my biggest fights with the pain I have been in has been around taking meds that I feel stop me from being Me, turn me into a zombie, change who I am a little and I have Hated it. I don't say that very often, but I have gone through a seesaw of resenting it, feeling so upset, stopping them, regretting it, returning to them, regretting that, coming off them. But, you know that there will be a time when you will stop these. Cling to that, and Go Steady.
