Addiction - how long should swim wait after doing H to take suboxone

[mullet0224]

SWIM has developed a small habit of smoking black tar

and he got a job and he starts tomorrow

he bought some suboxone off a friend that he wants to take to ease the withdrawals enough to get through work thursday and friday, since he has weekends off

but he heard that if you take suboxone too soon after doing H it will make you start withdrawing instead of easing the withdrawal
so how long should SWIM wait to take the suboxone so that it relieves the symptoms instead of causing them to get worse?

also, SWIM has some vicodin. if he takes just a few vicodin, it tends to help him sleep for a few hours during withdrawal. will that make the withdrawals last longer since its an opiate?
