Sure I can stop...I go w/o marijuana quite a lot. Marijuana isn't physically addictive & it doesn't bother me one iota when I don't have it, & that's one thing I love about it. I don't drink 'cuz I HATE the taste of alcohol & it makes folks turn violent, & that isn't my style.
Now for tobacco, that's a totally different matter--it took me 5 MONTHS (using a nicotine patch) of going thru pure hell b4 I began to feel confident that I had kicked the habit. It messed up my sleeping pattern severely, I had the shakes, stomach cramps, loss of appetite, severe headaches....it was terrible! It's been a lil over 2 yrs since I've had a cigarette, & even now I could go back on them 'cuz I miss it (I still feel like one of my best friends had moved away or died).
I pray you can go without marijuana again. If it's easy to stop, you should be able to. Hopefully this can happen.
BTW, I smoked for 2 years and gave it up at the drop of a hat. No problem whatsoever. From your experience, you kicked nicotine. Can you kick pot?
