I've tried the seeds before, I chewed so many that I got salt sores or something inside my mouth. maybe I should've gone to unslated but those taste terrible. Now I've gone to sugarfree orbit regular gum when the nicorette isn't shoved up into my mouth.
Just a note, David & Sons has come out with a low(er) salt version of seeds, if that helps. I've heard the oral fixation problem is a big one to overcome. There are some inhalers that some people use to help with this.
