This is odd. My pharmacy couldn't locate 200mg tabs anywhere and asked me if taking 2 x 100mg was OK. I thought it was. Ugh. I've had nothing but trouble with my meds this month. Insurance formulary change means they won't cover the number of Xanax tablets I get. Lithium increase, insurance won't cover the new amount until next month. I guess I'll just be anxious and manic for a month. I wander if they do this for people with other illnesses.
