"i&#039;m 24 and i work in a -20 freezer selecting orders for groceries stores. constant bending and lifting while briskly walking. 3 times a week in 8 hours i&#039;ll take tramadol and one or two 10/325 percocet. that cocktail gets me going. loosens me up, no pain in back our feet and it numbs the cold out. i could run for 9 hours with it."
