"i have been on this as needed for the last 4 years. i started at 0.5mg and am currently at 1mg. i only take when needed and have not had any negative side affects. i only wish it actually lasted longer. roughly last for 30 to 40 min. i have taken to help sleep, i am a war vet and it helps to calm down the hyper vigilance. i have seen people struggle coming off of this, but they &quot;usually&quot; are the ones abusing it.  it is not an everyday med."
