I take a regular dose of 5 drops on an empty stomach and then have breakfast..
Works fine for me.
Citric acid can be obtained everywhere: Don't go to the chemist but to a store where they sell stuff for wine making.
Citric-acid is used in many things from homemade lemonade to de-calcifying your coffee-machine.
It is used in winemaking and it also is a very important part of your metabolism.
You couldn't live without it and even if you would swollow a pound you wouldn't even get sick.
Try buying citric acid on-line.
Here in Europe there are many ways to get it and it is very cheap as well.
And I must say: The results with citric-acid are the best.
And as I said: Try to de-calcify your coffeemachine with it or your watercooker.
You will be surprised because they will be as new.
