I am feeling tired and drowsy the whole day. Sometimes I feel giddiness. My doctor said my thyroid and hemoglobin reports are normal.

Tiredness and drowsiness with normal thyroid and hemoglobin could be due to low Vitamin D, B12 or iron stores. Lifestyle stress or sleep issues can also add. A simple deficiency test might help.

I consulted a doctor because I was having balance problems and vertigo, and I was told I have a vitamin B12 deficiency. My test result showed a level of 193. The doctor prescribed Neurobion Forte, Monobe (thiamine), and a multivitamin. I have been taking these medicines for the past 22 days. Although my symptoms have improved, I still have some problems. How long will it take to fully recover?
