I started clen a little more then a week ago and im up to 6 sprays of this sites clen... so im guesssing thats about 120mgs? i get a few hard headaches and shake all day but nothing i cant handle, can i bring up my doses? or should i not and also i was wondering if it was alrite if i do my cardio of the day about half an hour after i take it because i take clen as soon as i wake up and do my cardio on an empthy stomach, is that alrite?
