Man these posts are wicked, the last few. I like when I can relate to subtleties and nuances of cannabis and associated strains, help me confirm for myself that my thinkin is right about the dope. The withdrawal is not subtle. It can be viciously brutal, in fact, and last a long time. I have even experienced post-acute withdrawal symptoms come back 9 months later.
I quit for 3 years in my 20's, and it took 6 months to feel anything close to normal. I vomited at least 15 times while detoxing too, lost weight as fast as I do in benzo withdrawal, and didn't sleep for I don't even know how long. Long enough to need an anti-psychotic for a bit. I was unable to eat even fruit at one point. It was also so stressful that I developed a long term panic attack disorder. It is often best to cut back as slow as possible while accepting you are a pothead for the time being. This way, the weed will slowly start working better, have less side effects, and you'll feel rewarded. Weed only really fucks my life up if I smoke it any more frequently then a toke every 4 - 6 hours or so and keep it out of my mind the rest of the time. Like next time you want to smoke, try smoking an hour later. If you have friends who blaze they will have to get out of your life for a while and will never really be safe to be around again, or you could make it a rule to only smoke socially (although if you are like me and many others, I prefer to smoke alone).
Don't smoke if you are already high or were high recently. Watch your diet, you will have to change it. Stuff like complex carbohydrates are out of the question for me if I try to stop (I am trying, and keep messing up, to cut back at the moment at least so I only smoke 3 times a day)
Everyone will have a different experience, in fact I have personally had different reactions over my life depending on circumstances. There have been times when I have had to completely quit because of side effects. There have even been times when I dabbed non-stop, including 99% THC, smoked blunts, and had very minimal withdrawal, a few days of being cranky. There are times when I smoke too much weed and get in that haze which is nice but I never get anything done. There are times when cannabis, like it does these days, motivates me - and I feel stupid if I'm not stoned. It took me way too long to learn how to use it in a way that works for me, but now I figured it out. Bong. Straight up. Bong. The heaviest bong toke I can take, but spaced out as long I can from the last. In a healthy state of body and mind. This helps me quit as I get so high I won't chase it and it doesn't set any standards for the day.
Advice? FUCK the xanax man NEVER take it again EVER. That shit is the devil. I swear to you I'd be putting heroin in my arm instead if I could but the xanax you can get so addicted so fast that it will literally kill you if you don't take it. And you are a prime candidate, already being addicted to weed and having anxiety issues.
Just cut back on the dope. Smoke less? You clearly enjoy it. The problems are coming from you, not the weed. If you allow yourself to be less frequently stoned, your reaction with weed will change and you will be less dependent on it. Much easier said than done. If you are 17 though, if I were you I would honestly just quit smoking weed completely for the rest of my life. That is what I would do, and what I regret not doing many years later. It just totally interfered with my life in so many ways because I refused to put it down until people stopped giving me shit over it now I at least consider it, but keep relapsing so I will be blazing for life that is for certain. I have not ran out since 2 September's ago.
I regret going back. I love weed don't get me wrong. I have some beautiful outdoor right now too! If you are 17 as a 30 year old who started at 15, I highly recommend that you quit cold turkey and never look back if you can handle it without any xanax. Seriously. Do NOT fuck the xanax that is the only thing that is absolutely necessary to say here. That shit will slowly destroy your whole entire life and leave you feeling twice your age by the time you're 25.
Quit while you're ahead. You are already getting into xanax at a young age and in my opinion that is a disaster waiting to happen. Weed cannot ruin your life unless you allow it to. Benzos, even if you want to quit, result in literal FATALITIES from regular doses. They also take you on and off them like a toy. Never, ever trust a doctor unless I guess they are writing you 3 grams a day.
