I may be able to advise, R.e anticonvulsants.
My knowledge of neuropharmacology, and in particular GABA receptors, sodium channel blockers, etc. and other anticonvulsants like the GABA-T inhibitors, etc. is pretty damn extensive. And I have to deal with seizures myself. And I'd love to be of assistance to the PR.
I could recommend lemon balm tea for her. It will do no harm, tastes lovely, grows like plague and contains some natural inhibitors of GABA-transaminase. Its not a hugely potent anticonvulsant, but it isn't a teratogen. And unlike the rest of the brood, it doesn't fuck over memory, in fact, it contains some acetylcholine-modulating substances that IMPROVE memory.
Just boil a few handfuls of fresh picked balm in water, add honey to sweeten, ready to serve. I love it.
