hi ladies!! I'm 5w1d and have been having dizzy spells for a few days now.  I just had to come sit in my office and take a breather because I feel I could fall asleep at any moment.  I'm eating small meals and snacking to keep my blood glucose up, so I know it can be low sugar.  anyone having dizzy spells yet?  is it possible this early?
