I have to take this daily or I will be wheezing by a.m. and that awakens me. This keeps me from doing so by taking it daily.

Bought this because I have problems with my lungs, and it clears them up. It does what it promises.

Good stuff

Unfortunately I got a bad reaction from this product. I recommend to start with low doses (500mg every other day) to avoid the potential for side effects. Also, Dr. Russell Blaylock doesn't recommend to take more than 500mg a day if your mercury levels are high.
