At least two weeks but should be longer,
I went through it, sucks bad but worth it.
If you take some pain killers you can handle the pain, there will not be long term damage for a once only. I wouldn't recommend more than that for at least 3-4 weeks.
Oh I see date now you have 8 days, I would just dose up on pain killers and give it a go.
Cannot see long term damage from one time.
It will be a bitch for you to smoke unless you heal fast.
Good luck.
Memory, prophecy and fantasy
-the past, the future and the dreaming moment between -
are all in one country, living one immortal day.
To know that is Wisdom. To use it is the Art.
