Be very worried. Someone of your size, and the length of your smoking, yes be very worried. I would start pounding gatorade, not water, or mix salt into your water. So you do not die of water intoxication. I would also maybe take niacin, or just pound gatorade 6 hours before your test. Then 4 hours prior take a vitamin B so your pee turns yellow. You will be fine if you do that.
