thanks to all who have responded, iam taking b-12, however i may not be taking enough doseage. but i'm on two kinds of b-12. i do have some questions, i'm a smoker, does smoking make neuropathy worst? is neuropathy permant? i don't have health insurance and when i tried to get it, i got turned down due to the neuropathy. so i've had to pay out of pocket to see a doctor. can someone give me some tips or advice?
