If you've taken in that much hemp oil (you know it absorbs better with food, right?) it's probably the magnesium. What might help would be hemp protein in a glass of milk, ever see the magnesium content on that stuff? Also, natty peanut butter, and/or some sort of nuts or seeds usually helps a chocolate craving.
Failing that, greens, broccoli (I make this really simple side dish my husband loves, take whatever kind of dark greens are in season, boil 'em up but don't over cook, then toss in a hot pan with a crushed garlic clove and enough EVOO to keep them from sticking, top off with a splash of hemp oil and hempnut seeds).
