Is It Advisable To Run While On Xanax?

Hi. Have been taking xanax for about a month .5 mg somedays and .25 others. and on the weekends not taking them. I am considering trying 5-htp. If i take 5-htp at night and xanax in the morning will there be a reaction? Also I took .5 mg of xanax this morning is it safe to run a couple of miles or should I hold of training until later in the day or hold off until tommorrow?
