honestly, i get these horrible headaches when withdrawing from excedrin. i know that it's not a lot of caffeine, but i take two, then the next day when i DON'T take it, get a rebound headache. so i take more, then the next day get another rebound headache, etc. could it be from that?
not trying to downplay your symptoms at all, so please don't think that. just wondering if that might be a contributing factor.
