Whay is the minimum dose of lorazepam for an adult. i am taking 1 mg at bed time.is there any withdrawl syndrome if used for a longer period.

Variable: The dose of Lorazepam required for effectiveness varies with the person, because tolerance to it is possible. And yes, taking 1 mg at bedtime can result in your eventually having a withdrawal syndrome. Your additional info indicates you're taking Clonazepam as well -- and that you have "confusion, snoring, & weakness" as conditions. All 3 could result from heavy sedative use. See your doctor.
