im on my fifth day of clen and i took 80mcgs this morning before running... this hasnt been a problem before but i also drank tonight and got pretty drunk... i got home sobered up and fell asleep at about 3:30.. i woke up about and hour and a half later and i cant go back to sleep for some reason and i think its because my heart is racing right now... is this a problem or the usual and should i stop taking clen?
