a friend of mine abuses her ritalin..she takes the whole bottle of 36 mg qty 30 in a few days. This last weekend she added to her mix Norco 10-325 qty 40 and tramadol 50 mg qty 40. She is now coming off it all, freaking out, panic attacks, cannot breathe, freezing, sweating. Has been a few days since the last pill, would the danger of Overdosing be over ?
