Twocamaros, BTW I really wasn't trying to take anything away from your post just that nightprowler wanted to make this a sticky and there is already a sticky on Dilution method that is very detailed with a better method than just drinking a gallon & 1/2 of water and some B vitamins. You are lucky that you are very skinny too. If some people tried to drink just a bunch of water there is a good chance they still might fail or get a dilute sample. For example, there are better fluids than just plain water. Keep doing what works for you though and thanks for sharing but I don't think this deserves a sticky when there is a more thorough and accurate one already on the site.
