Your doctor is very wrong.
1.5mg of lorazepam is equivalent to 15mg of diazepam/valium and this amount needs to be tapered.
Can you go back to your doctor and tell it that you are suffering withdrawal and would like to taper off this drug in a safe way?
Read the Ashton manual to learn about what benzodiazepines do to the body and brain and how to get off them safely. Then, make a safe taper plan and then take this info to your doctor and ask for him to help you to taper off this drug safely.
Benzos should never be stopped cold turkey or abruptly. This so called doctor should know this.
Here is the Ashton manual and some other resources for info about how to get off benzos. You will need a doctor to prescribe the drugs and to supervise a safe taper.
