For the past 4 years I have been plagued by
symptoms which include chronic stomach pain, brain fog, difficulty swallowing, metallic taste, depression, insomnia, etc. I have seen over 30 doctors without a clear cut answer, and recently have been diagnosed with a b12, b5, zinc, folate, vitamin d, and vitamin c deficiencies. Could these deficiencies be the reason for my symptoms? Right now I am taking about 12 vitamins a day and have been for the past 3 weeks. When should I expect a recovery?
