You won't be able to do it with that attitude!! You won't lose it totally and being negative
Some might ask why you have to quit the pot in the first place! I assume this is job related. Again, that's a good reason but not the right one. You need to do it for yourself and you need to want to!
If you could quit opiates and meth then you're pretty strong! I think you're asking how you can get through life without any "buffer". Well, you can and a lot of people do it everyday.
When you find the reason why you want to alter your perception and reality, address it and go on drug free. Using/abusing any drug is only a symptom of a bigger issue. Get to that issue...
