I am so sorry to hear you are struggling so much, it is a struggle all of us here can relate to.
Its not necessarily the most popular opinion on here(my opinions and personal experience regarding meds, and i am also very aware of the complications some medications can cause including but not limited to opioid induced hyperalgesia, for me this falls into the category of what works for one or most may or may not work for you, and for me personally pain medication is effective, and whilst many will disagree, to assume someone is addicted is a bit harsh, because for me when im not having a flare up, my pain meds go right down, and is also something monitored very closely between myself and my gp), but i personally feel that its about finding what works for you. And for some of us(myself included, i take a large amount of various medications) medication is part of what helps make living a life possible, for others the side effects are horrendous and savage, again its about finding what works for you. My current cocktail includes:
Celecoxib(anti inflammatory)
Orphenadrine(muscle relaxant)
Amitriptiline 125mg a day
Diazepam, tramadol, codeine and panadol in varying amounts daily
In addition i also take high doses of magnesium, vitamin D and E and monthly b12 injections which i now administer myself to save me 15 bucks for each time. As a result i also take a herbal based bowel supplement as im not able to poop if i have to push, as i cant push from a mixture of muscles not working right and just not being able to push.
I have also tryed the following diets:
Low saturated fat
Dairy free
vegetarian
fully plant based
I have put 1.5 to 2 years concerted effort in trying to go medication free, this was something very important to my partner(that relationship has since failed in large part due to my health issues). I take my hat off to those that find successful ways of managing there health medication free, that has not been my experience.
It has been my experience that its important to try different things as more often than not its about a multifaceted approach and in finding the things that help even a little and when you find enough things that help even a little, put altogether, help alot.
For me, my biggest piece of advice is dont stop trying to find new things that help but also dont beat yourself up if medication is a part of that(a big part or a small part, a lot or a little meds). Everyones journey is different and what works for one of us with FM might do absolutely nothing for another person with FM, find what works for you and dont apologize for it.
My relationship ended in large part due to my partner not being able to deal with my health and all that entailed, the biggest thing ive learnt and taken away is that i have found the things that work for me and i will not apologize for it, nor will i apologize for beinf sick. Find what works for you and know that you arent alone.
