Query: worked but hardly any in the bottle.

I purchased this not even 2 weeks ago and I'm already out of it! I used one teaspoon per day and it didn't last long at all. It did work as stated but when I opened the bottle there wasn't even a fourth of the bottle full. Even though this worked I will be shopping around to find one with a good price and better supply. Disappointed.
