My friend has been on 280mg methadone and xanax (?mg) for years to treat her chronic pancriatitus... Granted, she lives where there are horrible drivers as is, however, I can't help but feel her driving only makes, what's already a bad situation, worse.. Nonetheless, she defends herself/her driving from a place of plenty fine articulation, as for how it's always the other persons fault, aside from her defensivness, in and of itself, around the topic in general.. Anyways, it became apparent that I feared for my life each time I got in the car with her.. I'd appreciate any insight into how these drugs truly may be effecting her judgment, regardless of how cognitivly communicative & 'with it' she, otherwise, seems to appear/come across? Thank you for your time.
