Joe, welcome. I understand the fear. You dipped for four years. I dipped for thirty years.
Fear made me quit. It made me weak in some ways, such as crying on the phone to the lady in the dentist's office when I made an appointment. I quit and my mouth started hurting and that lasted at least two weeks. Jaw, tongue, gums, throat, and even my neck...which turned out to be lymph nodes screaming for the tobacco poison I'd fed them for decades.
But, the fear made me strong, too. It made me decide never to use tobacco again. I'm stronger today than I've ever been in my life.
Go to a dentist. Be completely honest with the lady who answers the phone as to why you want the appointment. The woman I spoke with set me up for an hour-long appointment and the dentist sat and just talked with me for about half that time, which was a strange experience in a dentist's office. Usually they just clean your teeth and out you go but this was very different. Tell the dentist if you drink alcohol too and ask him what he thinks about the combination of smokeless tobacco and alcohol.
The best feeling in the world is hearing you don't have cancer.
But, like not using tobacco, that is only for today. Still, it's the best thing you can do, especially right now when you're scared.
I know the fear you're feeling because today is only Day 31 for me and I'm still scared, but going to the dentist was a great thing for me. Do it.
I'm going on too long now so I'll close with this: I wish more than anything that I would have had the guts and the wisdom to quit when I was your age.
Go post roll and stay strong. Read a lot here and make some friends and keep your word.
Best wishes.
