You'll only be flushing money down the toilet if you pop pro-biotics in a capsule down your throat.
they pretty much have to be brought back to life and awoken in some sort of a sugary solution, such as juice, before consuming.
If you were allergic to probiotics, you would be dead since the majority of your body is made up of bacteria and yeast.
If you culture them for 2 or 3 days you will feel a major benefit within minutes, if not moments of consuming.
If I only knew years ago what I know now know about the proper way to use probiotics.... there would be so many doctors with so much less money. But, perhaps there were other things I needed to learn first.
