That's the way I did it and I had good results. I didn't have problems with sides, so a morning dose was no problem for me. Others, who had bad side effects (especially extreme lethargy) preferred to dose the entire amount prior to bedtime. That way, they were able to sleep through the worst part of the lethargy. So, try it split, if the sides kick you too hard, then try dosing at night before bed.
