i have been taking a antianxiety medication since i was 18, (valium for6 years) xanax when i moved and had a different doctor. i have been taking xanax for 26 years. the highest dosage being6mg.-8mg. i did not always take the higher of the dosage, but 2 times i did not take it, and ended up having a siezure both times. (never had a siezure in my life before that). can i have a siezure , by staying ON my medication? i was told by a cna who is trying to wean me down to 4mg xanax daily (which truthfully i am having a hard time at 5 mg.) a little family background, my mom took valuim since i can remember and grandmother took lithium up until the day she passed. is this a hereditary trait? by the way my cna has me taking cymbalta 90mg. daily (and wants to up the dosage). i have never had any problems TAKING xanax, just going OFF xanax, is there a certain dosage where you start having siezures? i was fine when i was taking the xanax for all these years, in fact my husband didn't even know i was taking it, until i was put on his insurance. i know i have a few questions in here, sorry, but i really need answers, before my dosage goes down any further and then i know i will be basket case, becausegoing down to 5mg. has been hard for me. thank you in advance, cindi
