Has anyone used "cleaning drinks" or "masking agents" to pass urine test?

This question if for THC. Has anyone here used one of those special drinks to pass a pre-employeement pee test? If so how did it turn out? Which one did you use? Unfortunatly my glaucoma medicine doesn't go well with my potential future employer. But I have ~3 weeks to clean out...however it is suppose to take 1 month to completely clean out the urine.
