My husband has bi polar disorder and was prescribed lorazepam 2mg (I'm in a country where psychiatrists give this high a dose) . He has been taking it for over a year, daily and it has helped tremendously with his mood. 

Does not drink or anything like that. Wondering if there are long term effects, should he continue to take for medical reasons? Or do the negatives outweigh the positives. 

Any advice would be appreciated. Please if you don't have anything nice to say, don't say anything at all. We are all just trying to get by.
