Wow! I'm currently taking or have taken meds that are found at all the different levels. I took Robaxin for years and that has a score of 3, Zyrtec is the only allergy medication I'm not allergic to, but it's also the least effective one, but I've taken that. Flexeril, Xanax... Tergotol is one I'm currently on with a score of 2. No wonder sometimes it feels like if I didn't have half a mind I would have any mind at all...
But honestly I'll take the cognitive defects over muscles spasms any day of the week. Frustration and annoyance about not remember the past 5 minutes seems preferable to the pain I'd be in without my meds. But it's still great to know the risk, and to be able to make an educated gamble.
