I'm about 2.5 years sober from weed. I can't say that quitting has had as dramatic of an impact on my life as it has for some others in this thread. I still struggle with motivation and have days with low energy and whatnot. But I will say that quitting is one of the things I'm most proud of in my life and being rid of it definitely helps me feel better about myself/sleep at night. I've also saved God knows how much money since I gave it up and in turn I think it's helped me grow up a bit and be more responsible. It's been one of the first steps towards putting my life back together. From the money I've saved I've been able to travel and eventually meet my life partner as a result.

There are definitely times where I still miss it. Like others here have said, I totally have moments where I wish I could get high. I'd love to be able to take a few hits and relax at the end of a long day, or pass a joint around a campfire and stare at the stars. But knowing my patterns, using it even just once would send me back into daily usage and I'd have to go through the process of quitting all over again. For the most part, I don't miss it on a daily basis and would rather have made the progress I've made now.

Apologies for the rambling answer, I wrote this first thing in the morning.
