My doctor recently prescribed me Lorazebam (1mg) after having gained a tolerance to Ambien (10mg). If you remember my past ambien thread you will know that i tripped balls my first time taking it (during a research paper too). Anyway, i'm not in the mood for any more "pleasant surprises", so can anyone contrast Lorazebam with Ambien? Also, is Lorazepam similar to xanax? Thanks in advance to those who reply.
