I posted a reply on " chronic fatigue or what ??" post.

Please read it - you might find similarities to yourself.

My wife was diagnosed as MS but last year we discovered she's actually b12 deficient - she gets injections which have helped so much.

I got impression you live in UK? If so doctors may not be able to do the B12 blood test - it's quite controvertial over here!

Get superior b12 3000mcg lozenges (methylcobalamin) and take one a day for at least 3 months. If you have b12 deficiency you should see an improvement in your symptoms.

B12 is naturally occuring, the main source is meat (liver and kidney) but if you have an absorption problem your body will never get enough through diet (however good it is). The lozenge dissolves under your tongue and B12 goes straight to the blood so bypasses digestion ( I think ).
