Sounds like you are managing and doing so much, with your grandkids, work, marriage and church. I’m pretty new to this forum also, and also have not yet been technically diagnosed (have appointment next month at Stanford for that), am also tired all the time like you.
I would like to offer you encouragement, and I hope that like me, reading the encouraging posts here will offer you hope for feeling better in the near future. I think Meow has a good point about considering (and perhaps floating past your doctor) the possibility of chronic fatigue syndrome in addition to a Fibromyalgia diagnosis (I need to consider that possibility to come to think of it, so thanks, Heather!). On the other hand, I read recently in a Fibromyalgia literature review, that something like 60 percent of people with Fibromyalgia also suffer from sleep disturbance as well as chronic fatigue symptoms. So I think the syndrome of Fibromyalgia includes the possibility of chronic fatigue symptoms, without your having to have a separate “Chronic fatigue syndrome” diagnosis (hope that makes sense).
There are so many possibilities for you to try, when you read this forum! On my end, I can recommend CBD oil for pain and sleep if your State has legal medical and/or recreational cannibis, tylenol for pain, lyrica for pain, cymbalta for pain and depression, light pool exercise (especially in a therapeutically warm pool) for pain and depression and increased energy, opiates for when the pain is really bad. Others have had success with other meds or modalities. How is your sleep? My psychiatrist thinks all the fatigue effects of fibromyalgia have to do with poor sleep. I’m not sure that is true for me, but I know my sleep is crappy. Oh, I should say I think melatonin at night is a bit helpful in that regard, hard to say.
One more thing, if you get real desperate like me, regarding the extreme lack of energy, I am now trying long acting adderall also for that and my hard to treat depression, which my psychiatrist is prescribing. I have finally conceded that it helps my depression and gives me more energy (mostly helps me with mental energy but even some physical energy). I have to be careful with that drug as too much and it interferes even more with my sleep. Anyway, I’ll try anything at this point. Fortunately, if you are open to trying new things and medications like I am, there is a lot out there for you to try! So there is a lot of hope.
I know you will feel less alone in reading this forum! I wish you all the best and welcome to this forum!
