take both at the same time, the half life is so long so you will feel it the whole day and into the morning the next day and maybe even longer. with no benzo tolerance at al i think it will give you a nice mood lift especially if you have stress or anxiety. I remember when i took 20-30 mg alprazolam a day, i was sent to rehab and were clean for 2 years then i was sent to a mental hospital and they gave me 15mg of diazepam. I was walking on clouds :D i think it was the most wonderful benzo experience i've had.
