Some people are saying that it had to have been intentional or that he was a prescription drug addict. However, I don't really buy that. When you are ill, your mind doesn't work quite up the standard that it normally does. And honestly, if no one told him about the effects of mixing them (which is probably what happens), he took his two anxiety meds like he would any day but then added the other meds for his insomnia and for the pain he was having. Most likely, he didn't even think twice, especially with being ill and jet-lagged. I think that they should include the drug information leaflet with drugs that you are prescribed here. I have never received one of those here and the pharmacist has never asked me what other drugs I may be taking. Very worrying.
