LSA is toxic on the liver, I would not recommend in general and it's not good effects. LSD would be better health-wise, but since you have the issue of seizures I would not recommend it under any circumstances.
This is psychedelic section, are you looking for any drug, or a psychedelic drug?
Are you epileptic as a result of drug use, or have you always been? Typically life-long users are already on a drug to prevent seizure. No real medical professional is going to advocate any drug beyond your prescription and this is a harm reduction forum. Even non-epileptics suffer seizures with high dose psychedelics - mushrooms are a well documented example.
Looking at your post history, I would not advocate anything. Try exercise.
LSA with a seizure history? No, avoid.
