i had gotten my test done on friday and i had to wait until tuesday morning....the waiting is the most intense insane feeling you will ever had....i had exams i had to study for and i could not even study because i was waiting for my job to call.....it was horrible. Take a xanex and lay down as long as you can.... Good luck...(never had the saliva test..) go to the pass your tests websites and find the time frame for saliva
