I bought mine at:

I felt they were the best from everything I read. Yes, things are bad for me again right now even. The gaba medication worked great for one whole week, however, it has stopped working and I am back on the couch at night sleeping one hour and putting my feet in cold water every other hour. I guess I have to call the doctor Monday and let him know it stopped working.

I have not noticed anything from DE yet but I am pretty clean with detox stuff so maybe it will take awhile, it has only been a couple days. I do not see any reason to fear taking this after reading/researching it.

good luck
