Don't let unknown fears stop you from quitting. You could be like my husband and quit with little to no problems. You won't know until you try. So far so good with my lungs. When I went to my doctor for help, he also ran tests, X-rays, blood work etc. Don't make excuses to your self on why you shouldn't quit either, your better off quitting now then later, it will just make it harder if you wait. Why did I quit after all those years? Well first I tried and failed many times, but I really believe the Good Lord intervened for me. One day after catching a buzz, I got so paranoid( never felt that ) and I was so freaked out ( thank God I was home) and I thought I was going to have a freakin' heart attack. I flushed about a half an ounce down the toilet and said enough is enough. Last year I never prayed so hard in my life for God to help me get through it! There were times I was so mad at Him, because I suffered so much emotionally. But I soon gave in to the thought that it was happening for a reason. This year I realized that maybe I could help others with my story and knowledge, about an addiction. So after learning how to use the computer, I researched the bad effects of marijuana, and joined in on forums like this one, to help anyone and everyone I can. So from the bottom of my heart, anytime you want to talk, want encouragement, a computer to cry over, advice or anything, I'm here, just a message away!
Good luck to you Nlee, I'm here if you need me, take care, I hope we talk again.
