Took .5mg ativan (lorazepam) 6 hours ago for bad anxiety attack can i drink a glass of wine ?

No. Alcohol will add: to the Central Nervous System depression caused by Ativan (lorazepam). The combo could cause shallow breathing, or worse. Wait at least 24-48 hours before considering having a glass of wine. Alcohol worsens your heartburn & vomiting, also. Have you seen a gastroenterologist & had an endoscopy to look for the kind of damage to your esophagus from longstanding reflux that can lead to esophageal cancer?

Risky: There are no serious professionals who will sanction it. The potential for danger is significantly increased. Both depress central nervous system functions and that's bad. Here's what they say: http://anxiety.emedtv.com/ativan/alcohol-and-ativan.html Your intention of 1 glass might slip into more and passing out can go further into places you don't want to go. Your delicate gut might not be happy.
