Do you think your meds are doing this memory-loss thing? At one time I went through 5 mos. of hypo mania & then crashed horribly into depression (& did some rash things) so meds provider put me on a lot of sedating meds to try to get me to sleep--didn't help much. I would go to sleep right away, but couldn't stay asleep for more than 3 hrs. I did find if I talked to my kids on the phone after taking my night meds I would have a perfectly reasonable conversation w/them, but didn't remember it at all the next day (also did the "sleep walking eating"). Needless to say it scared my kids (grown) & me so that I wouldn't talk on the phone after taking my night-time meds. Luckily, I've gone through some EMDR therapy treatment so have been able to get off the sedating meds for the most part--but it is scary to know you did stuff & can't remember it at all.
