Help me with decision please!

Hello and thank you if you are reading this. My 8 month old son last week started having what doctors the past day calling seizures. They look like he is just angry and shaking a bit and they last mostly 1-2 seconds but have seen one last 4 seconds, in the past week hes had maybe 1 a day or upto 5 a day, he doesnt close his eyes when they happen, vomit, urinate etc and he also doesnt seem effected from them afterwards and goes straight back to playing, laughing etc. All his tests came back fine blood, EEG ( he had one of these episodes while getting the EEG and it still came back fine), hes been in hospital since last week. They said at 1st it was possibly a viral infection, yesterday they said it could just be a "unknown" thing that will pass.....but now today...they want him out of hospital tomorrow and to put him on epilepsy medication! I feel like they just cant figure out what is wrong with him and want to label it epilepsy and get it out of the hospital(NHS), they want him started on the medication tomorrow too. This is what is troubling me, i really don't want him on the medication that lasts two years for the simple fact it might not be epilepsy, and this "episodes" might simply leave his system and hell get back to normal...but if he takes the medication and still goes back to normal gradually....he'll be laballed he needs the medication because it helps :( My girlfriend and i argued today about it badly, she wants him on the medication and i dont, i want to wait a week and see if he improves naturally instead of feeling he's being a guinae pig to test drugs on from the hospital....its ripping me apart!
