It's 7pm now. Throught yesterday I took 40mg of diazepam in 3 pieces, morning, lunch and before bedtime. I heard it's half-life or something is pretty long, like 100-200 hours or something, but it's effects only around 8 hours. I was planning to drink tonight and want to know if it's safe. I know mixing benzos and alcohol is bad, but does that apply to the effects time or the time it's completely out of your system(the half-life thingy). Right now it's been about 20hours after I took 15mg of diazepam. I'm not on a diazepam long-term cure or anything, It was just one day trying it.
