I have some diazepam for extreme anxiety. I wanted to take some last week but got too worried incase I felt drowsy, so I didn't bother. Today my anxiety is really high and I need something to take the edge off. I have 5mg tablets (only 4 of them for emergencies) however I'm worried they're going to be too strong for me. I've taken diazepam before, but it was around 18 months ago now, I took between 4 - 6mg and can remember feeling quite drowsy but I'm worried that one 5mg tablet now is going to cause me to become really drowsy, mainly because I haven't taken them for 18 months or so.

So my question is, is 5mg a strong dose? I really would like the edge taken off my anxiety today but I'm so worried about feeling really drowsy or out of control? Thanks.
