I'm very fortunate. My problems are pretty minor compared to lots of folks here, and I think I caught the problem before much serious damage happened.
I had very mild symptoms (occasional RLS) all my life. About 15+ yrs ago I started occasionally getting night-time twitches -- I'd wake in the night, agitated, with my arms/chest muscles twitching, couldn't go back to sleep for an hour or three. Drove me crazy. At first calcium/magnesium kept it under control, but over time it got worse and cal/mag quit working.
Then about 2 years ago, things got lots worse. I don't know if it was age (I'm 58 now), or reactions to depression after my divorce, or what, but it was no fun. I had RLS most of the time, I had skin-crawling and crawl-out-of-my-skin sensations, unpleasant tingling/energy in my legs, full-body flight-or-fight type agitation. That drove me pretty bonkers and made me very irritable. At night I would get an hour or two of sleep, then I would wake with twitching that escalated into full-body thrashing like a beached fish. For 3-5 hours every night I was tearing the bed apart, in a state of either extreme agitation or semi-awake nightmarish terrors. Full body "feel like $#|+" reactions most days, like a bad hangover. It *sucked*.
Fortunately, within about 6 months or so I stumbled onto B12. 500-1000mcg per day of methyl B12 (Readisorb spray) **totally** erased all symptoms. No RLS, no agitation, no muscle problems, no night-time horrors, sleeping soundly 7-8 hours every night. It was miraculous.
Apparently I continued to get worse, and after about another 6 months my symptoms started coming back. That's when I started doing more research, and I ended up here.
Now I'm taking more B12 (1.5-2.0 mg/day methyl and 4.5-6.0 mg/day adenosyl, net usable absorbed from transdermal oil), 1.25-1.50 mg/day methyl folate, and a bunch of other stuff. I tried l-carnitine fumarate but I didn't notice any difference.
But the B12, and to a lesser extent the methyl folate, is critical for me. I can feel VERY clearly when I start to run low -- the muscle-crawling, twitching, agitation, etc start up. I feel near-instant relief from those symptoms when I take more B12.
For a while I was using sublingual B12 -- I settled on Country Life 5mg. But there's very low effective absorption from sublinguals. I was taking 25-30mg per day and it wasn't keeping my symptoms under control. I would frequently have a bad night, and take 1 or 2 more 5mg CLs to try to get back to sleep. Then the next day I would feel weak, shaky, full-body ick.
I tried injections for a while and (for whatever reason) that didn't seem to work at all well for me. I tried injecting as much as 3mg/day of methyl B12, with very little effect. I couldn't discontinue the sublinguals, so I didn't see any point in poking myself every day.
Then I found out about the
Aussie transdermal oils, and that's been a Godsend for me. The oils seem to deliver the B12 much more effectively than the sublinguals -- and I don't have to have a mouthful of pills all day long. It's not perfect but it's doing a really good job of keeping my symptoms at bay. I use 3-4x the "recommended normal" amount, but that's what it takes for me. It's costing me about $60/month but I'd pay that all day to get relief from my symptoms.
