Make sure your doctor is prescribing the correct equivalency of Ativan to Valium. 1 mg. Ativan = 10 mgs. Valium. This is extremely important so that you have a smooth taper. Too many doctors want to under-dose when making the switch. I didn’t find that Valium made me sleepy. I did find that it relaxed my muscles too much. Please google the Ashton Manual. You will find a step by step guide. Hopefully your doctor will pay attention. Most do not. Do not under any circumstances let your doctor rush your taper!!!!!!!!
