^ it could very well be the problem. As of recently,I discovered she's been rx'd UP to 200mg of Tramadol (which Tramadol is like kryptonite it me, being on Methadone) per day- now I don't know if she takes the 200mg everyday...this was all news recently came out. She's also , as long as I've known her been on anxiety meds- From Xanax, Valium and Ativan who know if she's taking any other pain meds. She was quite upset that her meds were more or less "known" since the seizures. (Personally, I can't help but shake my in head in pure amazement with this knowledge due to the fact that I have always had to hear the "disappoint" and "embarrassment" and pretty much disgust that she&and my brother have had for me over the years due to me being on methadone... The irony. Now it makes sense why she's always so spacey, flighty and downright droopy-drowsy. My mothers noticed this too. FB No wonder she was mad that her meds came into our knowledge! Sorry, off topic). SO, I know she goes to ER a lot with pain- don't know what else she gets rx'd. I do believe it could be a VERY likely cause for seizures. I don't know HOW honest she's been w/her Dr's/hospital. But the mixture of meds- if taking the max. ammt. or more, then your more likely in a zone where a seizure is a total possibility. Scary.
(Side note - never throw stones-it may come back on you 10 fold. I will never bring up the names they've called me, for being on methadone, I figure that w/her&my brother knowing I know, with no words from me is... torturous enough

)
...but I in no way, even giving the karma of judgement, do NOT wish for her to have ANY seizures. Just want to clarify that! The karma is her knowing I know.
So, yes, I do believe there's a GOOD damn chance the mixture potentiated seizures.
