I have taken 1, (0.5mg), Ativan for at least 8 years as prescribed by my doctor. He prescribed it after trying many other anxiety drugs. I have never used more than 1 pill at bedtime. It has helped me sleep much better and kept my anxiety at a livable level. I might add that I also was diagnosed with sleep apnea around the same time. I also have high blood pressure. The Ativan seems to keep me calmer, and much more alert the next day after taking it at night. My question is, is there any long term harm from taking the drug?
