I have a few 2mg diazepam tablets which I was prescribed for fear of flying last year. They made me feel a bit more relaxed than usual but I still felt very anxious. Now I have something coming up tonight which I am TERRIFIED about and my anxiety level is already extremely high - I am going to take one of the leftover tablets but do you think I could safely take 2, ie. a total of 4mg? I don't think the 2mg will be enough. I know I should ring my GP to ask but it's a bit late notice and I doubt they'll get me an answer by tonight. Plus I really don't want to get into it all with them on the phone...
