1M+10M dose question & smoking, narcotics

Hello,

A homeopath determined a constitutional remedy (Causticum) and advised me to take the single-dose vial of 1M pellets under the tongue in the morning and then if there are no significant negative reactions take the single-dose vial of 10M pellets in the evening. This is supposed to result in a permanent restoration. I was wondering if this sounds like a good plan to other homeopaths - should the 1M be given a week/month to work?

Also, I was thinking about the final healing state and wondering about substances I'm probably addicted to. I have been taking prescription narcotics (Tylenol with codeine phosphate) for pain for over a year and it seems like if I stop, there will be substantial withdrawal symptoms. Should I taper off the drug over a couple weeks? And does pain medication interfere with the homeopathic treatment.

Finally, I've stopped drinking coffee but am still smoking a pack of cigarettes a day. I'd like to stop but think this might take a couple months. Will smoking antidote the homeopathic treatment or restart the disorder we're trying to heal?

Thanks very much for anyone with the time to reply!
