Hi Joopiter, if you experience as well a kind of increased nerve sensation, increased "legs falling asleep Are you meaning increased tingling and "pins and needles" sensation or are you meaning completely dead/numb? If tingling and increased paresthesias of many kinds, that often happens with mb12 as the nerves start being more active and coming back. For me this increase usually leads to going through the onset paresthesias (neurological noise), that may have occurred 20 years before and be a distant at best memory, in reverse order until it goes through a hyper sensitive phase and then fades to normal. This can take up to a year or so. When I get a not so good batch of mb12 the tingling in my feet fades to numbness and when I get a better batch it increases tingling a lot. Feeling returns in little patches. In the past month I have regained more feeling in my toes and better motor control with most of the numbness now in my arch, which has increasing pain which comes before the tingling if it is already numb. These are the muscles I am talking about as I have feeling in my entire feet in the skin. I have always considered that the multisensory hallucinations were "neurological noise" from the lack of functionality and damage to the nerves. Where this noise happens determines how it is perceived and interpreted. also I feel that my eyes are like "confused" I cant look as clear as before, something is different I've never heard it described that way. I will describe what I experienced. In the months before I first started mb12 I had been loosing the ability to focus my eyes. My wife read the entire Hobbit and Lord of the Rings series to me as I could no longer read on many days. It felt like I had no control of the muscles of my eyes. The focusing muscles seemed to spasm, like the muscles all over my body and sometimes gave me horrible headaches. With the mb12 energy started returning to my all the muscles in my body and I began to be able to focus my eyes every day. The nerves and muscles were different than I had gotten used to over the previous decades. However, with use they started coordinating again. As the lack can affect the nerves as well, if one gets increased paresthesias (neurological noise) in the nerves to the eye it could cause all sorts of things. If you look at the list of b12 deficiency symptoms you will see many effects on the eyes. I'm not surprised that eyes might be affected during the healing process. Mine were, thank heavens.
