Self employed ind. contractor. Received $59/day perdiem for meals, included in income Box 7 on 1099-Misc. Does the 50% ded for meals on Sch C line 24 apply to perdiem?

Confused about the 50% meals deduction on Sch. C Line 24b as it pertains to daily per diem amount.  It is added as income to Box 7 on non-employee compensation and I think I should be able to deduct the full amount received as per diem?
