yes, you have enough time to clean out naturally.
Del, with all due respect, 1 week is not generally enough time for a daily user to clean out naturally. While I do conceed that it is possable, IMHO it would be the exception and not the rule, if J3MiN1 is able to pass after just 7 days, naturally. Now with dilution at 7 days clean, I'd be astonished if he came up possitive. But without dilution,...well. THen again, maybe that's what you're saying and I'm just not understanding your post correctly.
J3MiN1, please do a home test the day before the test to see where you stand. If Del is right, GREAT! But if you are still hot, be ready to dilute.
Hoping the best for you.
