Triazolam
"Triazolam (halcion) is great. In 10 years of use I have never built up tolerance to it but only use it when required. Upon average 5 nights a week. I break my 0.25mg in half and make sure that I am relaxed as possible when taking it. There appears, for me anyhow, to be a threshold of about 15 to 30 mins after taking it where if you get involved in stressful activity its effectiveness is reduced dramatically. Best used in conjunction with relaxation techniques."
