which vitamin b?

If it's after midnight, then I'd try to find a 24 hour gas station that sold a multi-pack of vitamins. Ususally these packs can be bought for a few bucks and has everything in it from Vitamin A to B12 and sometimes other suppliments. Whenever I take just B12, I get a deeper darker urine, but not a whole lot more yellow. When I take those multi packs (the mega man packs from GNC are my fav to use on a daily basis), I piss radioactive Mtn Dew. :thumbsup:

I'm assuming that you're attempting the dillution method. Just remember that you can drink too much water. Be careful.

try to grab a B complex (contains B12, B6, etc)... if you cannot grab a complex, B12 will do.
