I do take a iron supplement I eat a banana each morning for potassium so far it has been working

My blood levels ( of my meds) fluctuate. I've never hit zero though.
Is it possible that something else you're taking is interfering with the absorption of your meds?

My Epileptologist and I had a similar conversation about 2 years ago. She told me that a seizure study that was done about 5 years ago revealed that a typical Tonic Clonic seizure episode (1-2 minutes) uses the same amount of of physical body energy as an 8 hour aerobic workout. This is why I keep electrolyte drink mixes and drinks with me at home and when I travel. So I can sip on these when coming out of a seizure. Doing this will cut my recovery time in half.

Yes.it happens to me sometimes... its usually a very temporary thing... you levels bomb because of overworking the system... they did the same for me.. with the pills and diet
... but I noticed levels always go back to normal in a couple days.... also my kidneys shut down sometimes for the same reason.. just being severely overworked.. but everything seems to go back to normal within a day or 2.. provided no more Seizures
