Few months back I did my blood test and my but d and vit b12 was low in fact b12 was very low. Doctor gave me vit d for a month and surbex gold d for 1 month. I have issue with my sleep I try to sleep by 10 pm but some time I wake at 2 some time 3. After that I try to sleep sometime I get sleep before I finally wake up at 430 or 5 am. I do not have stress I do my yoga regularly except when I feel sleepy I cycle to my office almost every approx 5km total So not sure why I have sleep problem I do not have no sugar etc but have family history of that due to which for past few months I have stopped intake of sugar except i take fruits
