I am a 28year old female, i work in a very busy histology lab in a district general hospital. Recently i have been getting similar headaches and feelings i.e dizzyness and general feelings of that i cant keep myself upright, that i may have to lie flat on the floor. (which isn't ideal at work?

)
i had been on epillum (only for 6 weeks at the most) and then transfered to keppra and this has all happend oct 08 till jan 09.
Im not sure if this is till just part of transfering from medication to another one? i just was really concerned because im starting to feel like i did before the 2nd seizure? has anyone had this before?
can anyone shed any light on it? i would say im under more stress at the moment than i have been in the past (selling my house, being short staffed at work and just normal worries)
Thank you for listening
take care abi
