My doctor told me if was safe to take 10mg of valium till my ativan gets renewed at the end of the month.. i was hesitant till I starting getting panic attacks massively. I just took 5mg instead of 10mg. I haven't takes valium in a few years and wondering if it's normal to slow your heart rate down? I'm used to the ativan slowing my mind down.. so im panicing that my heart will slow to a stop while sleeping which is not helping me trying to relax out of a panic attack.
