jnn,
that is really a low dose...you should be fine coming off and depending how long you've been on it I doubt you'll experience much of a withdrawl as far as really uncomfortable symptoms. It's my understanding, from rehab & talking to docs, that the only drugs you can die from in withdrawl are alcohol and benzodiazepines (valium, ativan, xanax, klonopin). We feel like we're dying in opiate withdrawl but it won't kill us....there's many a time I wished it would though. Good luck and try not to worry. Talk to your doctor if you are really concerned.
Take care,
KEW
