I am sitting with a friend who is having a reaction from alcohol, marijuana , lorazapam ( 2mg ) and fluoxetine ( 20 mg). symptoms are: tachycardia 100-120 bpm, respiration 24, shallow but regular,extreme restlessness, nausea, muscle spasm & tremors. Last meds, the lorazepam taken approx. 10 pm yesterday. He has been suffering for several days but is refusing medical treatment. Will this pass if he puts no more alcohol/ marijuana in his system?
