Epilepsy, seizures, and estrogen?

[shared from r/AskMtFHRT ]

I don't have epilepsy (afaik) but I have had seizures in the past (6 years seizure free in February!!)

Estrogen does raise seizure threshold unfortunately, so my PCP is hesitant to okay me going on injections versus oral (I take mine sublingual anyway, after extensive reading on transfem science and other outlets). I know that I will be on E for the rest of my life, and I'd rather lower my liver load by doing shots, and it seems to have a better outcome on lowering T. My T currently is 172ng/dL as of 12/18/24, and I'd imagine it's lower since starting progesterone that week as well. (Currently on 8mg E sublingual, 100mg spiro orally, and 100-200mg progesterone rectally daily (sometimes I take 1 at night and sometimes 2)).

I don't want to be an asshole to my doctor but by now I would assume that E had a major effect on me I'd be having seizures again. I know that shots raise E high and then it tapers off over the course of 5-7 days (depending on dosage and frequency of shots, I would prefer 5 days). I have a neuro appointment soon and I'm planning to discuss this with my neurologist, but I feel like at this point I have a better grasp of the available literature and my own personal reaction to prolonged use of HRT. Should I essentially "demand" shots? I'm tired of waiting for the physical and mental changes and I just want to start being me after a long and varied journey of self-acceptance.

Any advice is welcome! Thank you all <3
