That's what I would do...I take 2 tbsps a day, one at breakfast and one before bed. But then I haven't had ANY side effects from the Acacia so I don't have to fuss about splitting doses up into 3+ a day.
Good luck! Remember that it can take a good while to see the effects...and if you get discouraged and stop taking it for a while it'll take even longer, so just stick to your regime, okay?
