I have used these FIZZY TABS for YEARS. NOTHING COMPARES to their effectiveness. I actually like the taste, and put it in 12-16oz. of sippingly HOT water. Can do this up to 4xday per the label. IF you don't like the taste, put it in 8oz. regular temp water and slug it down. Just take your medicine!LOL Of course, the sooner you take it, the better. However...there have been a few times when I've taken it, every 3 hours, once 'misery' has set in...and it was effective, either gotten rid of the sick or shortened it considerably. << I have tried the little 'Wellness tablets' and they do nothing. >> The packaging of the FIZZ TABS needs improvement. Are you listening, Source Naturals? Package each FIZZY TAB individually. I'll pay more. Just keep making this formulation. Meanwhile, I advise opening the tube(s) and emptying the tabs into a light-safe airtight container, such as an empty brown glass supplement bottle. If left in their original plastic tube, they may stick together rather solidly. This requires having to chop/scrape it all out. Then put into another container and guesstimating approx. serving of the powder and chunks. I would much rather do that than not have the product at all !!!
