when i was younger (im 28 now) i used to take lorazepam (ativan) recreationally. at times i used to take large doses 40mg+ with alcohol (maybe 20 units). i know how stupid this was but looking back, i worry whether i was ever close to overdosing? i had a really high tolerance and never had anything bad happen (other than bad amnesia).

i know the toxic dose of lorazepam alone is pretty high, but what about in combination with alcohol?
