Drug info - Bupe(Suboxone) Halflife & when to safely use again

[Wiknasty]

Swim had a bit of a H and OC problem for about 3 months, and decided it was time to kick the habit and was perscribed to 16mg of suboxone a day. Swim has been on this regiment steady for about a month now. Swim and his girlfriend aquired a a few OC 80's and Swim wants to have a holiday from Suboxone and just use for a day and then go back on the suboxone.

After doing some research Swim found out that bupe has a half-life of about 36ish(plus or minus) hours, so it would take weeks of being off bupe for it to clear his system.

Soooo.....
1)How long should Swim wait to use again, as not to waste the OC?
2)Will Swim's tolerance be sky high after being on bup for a month?(I was doing on average 1-2 80s a day or 4-5 bags before rehab. Also I have not used anything but the bup since I have been on it)
