i got some 100 mg at one store and 2000 mg or mcg? at another so i dont know what the right dose is

for two years ive had phn from getting shingles and couldnt sleep at times

ive felt for the last 6 days or nights ive been able to sleep because of taking b12

but i took a 2000 mcg b12 yesterday and sort of panicked or it was lack of air maybe or because of one beer

searching internet for 2 years i think maybe b12 is the best thing to take for phn

theres little info on it

i had it in eye and i dont know if its gone to my brain too but who knows

the version i have isnt too much fun

people that get it on leg i suppose dont have it as bad
