From personal experience, if you get away with it at the time, which I have, you just end up not feeling high but more DP'd so it's a complete waste of time anyway, I don't get the anxiety from weed like I use to, I just get no pleasure and more floaty and I get off light, I am what i'd consider a good case which still doesn't make myself even want to touch it. Plus 8 months, well it takes a year or two but you turn over a new leaf, it's just not something you do anymore. Your mental health is much more important.
I'm yet to read a 'had DP, went back to playing with the devil, it was awesome and i've been smoking for 10+ years and never been burnt again' story. As much as i'd love that to be the case, it simply doesn't seem the case, so forget about it.
I was a stoner (not how i got DP either btw) and I realised from having to distance myself from that lifestyle how boring it actually is, you are constantly not dealing with your life and getting high, there is seriously so much more to life. When I go to parties, i roll for friends, as that skill never has left but it no longer phases me, however a small room with that smell, i can't stand it anymore... and i know people without DP who quit weed and gives them the same headache I get..
You'll move on.. or not take this advice and seriously wish you did have. It's defiantly an addiction whatever you think about it. Doesn't mean that sometimes I don't have the same notion, mine isn't as much I want to do it currently, it's I want to do it sometime in the future (5+ years) and enjoy it.. but i'll have to practice what I and so many people preach.
