Want to ask this question in subject because once my FBS falls below 120, I am not comfortable, feel a bit week, get confused thinking and feel wavering. I am not taking any medication and on Keto diet for the past 45 days with FBS averaging to 121. So, want to know can I continue on 120 FBS. I read some where that the "Normal 80+" may not be the same for each person, but at the same time I dont want to take that excuse and ignore my numbers. So based on your experiences and expertise, please comment
