"i use this instead of xanax. it works and has no hangover effect.  my concern, however, is that a thrombophlebitis might have been the result of more that a month&#039;s moderate usage.  i did go to the hospital where lab work was done and a wet-scan ultra-sound was done, with no evidence of clotting.  i will continue to use it because it&#039;s more effective than any other product.
