Has anyone quit smoking marijuana? How hard was it, and how many times did you try? Is there any substitute (non-addictive) for when you can't sleep and are going crazy?

I was addicted to Oxycontin for 2 years and i detoxed from that in June, I am still taking the methadone daily from my buddy (we are both licensed physicians at a local hospital and he is my "Primary care doc". However, after going thru something as painful as opiate withdrawal, even medically supervised, quitting smoking ganja really isnt that bad.....PHYSICALLY, when i was quittin Oxy it was literally physically painful, but with chronic i just dont smoke, the only time it gets hard it when u cant sleep or when u get mad or upset about something. I also have stomache problems from the years of Oxycontin and Vicodin/Norco(by the fist full) so the marijuana helps with the extreme stomache pain and lack of apetite that i exerience every couple days, but now i just take some herbal remedies. here is a great list of herbal and OTC meds for marijuana-detox. here it is:
-Valerian root helps withn the anxiety/tension/sleep(local health or grocery food store)
-tylenol PM or exedrine PM for sleep
-protein shake/slim fast/meal replacement (to make sure ur gettin calories when ur appetite is nonexistant for a few days)
-PHYSICAL EXERCISE will work that stuff out of your system AND make you tired so you can sleep better.
If anyone had any questions on ANY drugs or detoxing from ANY drug, you can contact me (for free of course), and i can give you advice on what you can do with the resources available to you......it will save you a co-pay. of course i wont issue any prescription over the internet, but as far as were you can go for help, OTC or readily available alternatives, or ANY medical questions, i dont mind answering them, even if you are a CURRENT drug user there are TONS of different precautions you can take to minimize the risk of overdose, disease, and/ or accidents, if u ask me i think its rediculous how they charge people co-pays when sometimes all they need to do is ask their doctor a simple question or two. email me any questions at prizneeze@hotmail.com, my name is Dr. Shepherd, this is my personal email account so feel free!
