I just discovered today that Ativan is a benzo, I've been taking anywhere from 1/2 to 1 a night for the last 3 weeks so I can sleep while coming off the norco, which was going very well, until this morning when I woke up having this weird pulsating feeling in my body and head. I kept telling my fiance that I feel like my blood vessels are throbbing all over and the back of my head feels weird almost like a hang over without pain, a little dizzy, very strange and he said I wonder if it's the Ativan and I said but I haven't been taking any for the last couple days and he said, "exactly!" So I looked it up and sure enough, they are highly addictive and a major symptom is the blood vessels pulsating, couldn't believe what I was ready, damn! Something else to deal with now. I think, however that this will not be a long drawn out thing as I was not taking much and not for very long, at least I hope not. I'm sticking to the Melatonin and antihistimine and that's it, I'm so tired of this BS!!! I've been without the norco now for 10 days.
