hello, my exboyfriend is taking 1-2 pills of Lexotan 3mg every night, he also drinks beer every day and sometimes he smokes weed. He s been given the Lexotan due to a back problem and his lack of sleep. Ever since, his mood has changed, becoming extremely anxious, blaming me for almost everything and feeling danger in every corner we go (we live in a 3rd world country). Can that mix of beer, lexotan and weed be causing him erratic behavior, to the point where he is almost hallucinating danger everywhere? Thanks for your answer
