OMG, did I post in my sleep. I swear I could have written this OP!! I suffer from the same symptoms than you and I too am sooooo tired of sleeping so badly. I used to have such amazing deep sleep, went to sleep and woke up nice and refresh. Nowadays, I woke up with my tinnitus louder than my alarm clock (which I don't need anyway as always awake early) and pins and needles in my arms and feet that makes me wonder if I slept under the mattress rather than over!
Although not officially diagnosed as B12 deficient yet, I am pretty sure that this is what is causing all my symptoms and my GP is finally coming around this. In desperation, I started to inject myself two months ago and started to feel much better, but it only lasted about 10 days. I tried again, 3 injections, again better until again the symptoms came back.
I have been perimenopausal for some time now and a number of people have suggested the symptoms could be my hormones, even though I don't suffer from any of the common symptoms of the menopause but decided to give it a try. I've been on hrt for a month now, and so far, no improvement at all, if anything, it was worse at first. So back to B12 injections. If you are definitely deficient, one injection only is unlikely to make you better.
The problem as I am finding is that the symptoms could be caused by different issues and it then becomes a vicious circle. Are the symptoms worse because I don't sleep well, or do I not sleep well because of the condition? Last week, I had better days the day after I changed the patch, but the week before it was exactly the opposite. Saturday, I got up feeling almost normal, was so happy, got on with my morning, for the first time not feeling everything was a drag. By lunch time, the tingling, tinnitus and that overwhelming feeling drained was back.
I've started to keep a diary, including symptoms, sleep pattern (got the fitbit), whether my day was stressful, if I exercise (as I feel worse after I do, and now haven't for two weeks), and where I am with the hrt.
At least it helps a bit to know that other women experience exactly the same things because most of my friends going through the menopause talk about the sweats, hot flashes, anger busts but when I ask about tinnitus and pins and needles, they look at me like they have no idea what I'm talking about!
