Medication changes complicating seizure disorder- how long until things settle down?

I have a complicated health scenario- including a seizure disorder- which was pretty much under control- until my new doctor wanted to take me off Methadone.

I was all for that- but was a little uncertain about the rate at which he did so- from what I could gather it was within the norm to take me from 60mg. to 30 - to 15 - and on, changing each week- but as a result??? my seizures got worse- became grand mal and quite long- I had 3 trips to ER in the last couple of weeks-

He (most unadvisedly) put me straigjhtaway back on the 60mg. without any gradual additions whatsoever and gave me a breakthrough pain med that had seizure warnings.

???How long- should it take for my body to readust to the regular dosage of Methadone- ??? And do you know if Methadone affects the teeth or not?

(I tapered back and did the wisest thing I knew how to do- giving myself a little more at a time and stopped taking the break through med when I realized it was problematic) Also, it doesn't seem right to be 'treating my seizures with Methadone- I'm on now Valium instead of Lorazapam- and Neurontin and these help a lot-

I just got a call from a Neurologist who says I don't have reason enough to come to be scheduled with him- arf. Why is it up to mE to figure out everything and get the paperwork where it needs to go- these doctors don't seem to be doing their jobs at all. They should pay me- sorry to gripe. Suggestions? I'm worn out and the seizures have reeked havok with my memory. really.  

One more question? My seizures may actually be a part of a Dysautonomia condition- do you know anything about seizures or fits of this type and what kind of doctor to seek help from?

The other possibility is brainstem compression because of my other conditions.

Thank you,

Still carrying my rainbow,
