I have been taking 120mcg of clen for about a week now and have also takin it before about 2 months ago for a 4 week period. I also have xanax to help me sleep because of night time axiety. The other day I took one xanax with my usual 120mcgs of clen and it extremely helped reduce the heart palpitations I get while on clen. Would this be a safe mixture? Or would it take away from any of the actions of clen such as fat burning?Thanks!
