How long ago did you take them? And have you took benzodiazepines in the past. Info?
BTW I say cut it all now. I am not a pdoc but 4mg is usually the highest dose for klonopin/clonazepam. You should be okay. Do NOT drink on that! CNS depression and other dangers No other hypnotics or otc antihistamines.
Why did you take 5mg's? It takes up to 45 or so minutes for them to have the anti-anxiety effect. Thats why I ask if you use some sort of GABA1a inhibitors for anxiety?
