OK - silly question from erika time......and you wont know til you sit n ponder a bit...but....
Have you had enough to eat when this happens?
You can ground and centre, and that will help, and yes, Nova is right obisdian is a great help too - really keeps your feet on t he floor, but if you are low in blood sugar before you start, working in the light uses up MASSIVE amounts of energy instantly - i can't read or sit in circle unless i have had chocolate and/or cake first (and i don;t have a sweet tooth) or at the veryleast a glass of fresh orange juice - if i dont take in loads of sugar before and after, i get dizzy, nauseous and very disorientated once i stop doing whatever lightwork i am doing.
