Personally, i think i could stop instantly. BUT, i wouldnt be able to keep it up for long as i need it to stop my head aches and stop the pain from other ailments.

I use it medicinally and recreationally at the same time, but if i was only using it recreationally i think i'd be able to stop straight away. But i dont want to, i enjoy it, and it's not causing me any trouble, so even if i am addicted im happy to be addicted.

But i dont think its an addiction, more of a habbit. But it's like riding a great roller coster... why not do it again?
