I have a good pill cutter and I’ve been able to successfully cut in half tablets that were not scored, including Ativan

Just want to offer support for your insomnia and make sure that you are getting help with that in some other way(s) if you are cutting down on Ativan. Do you have another med to help you sleep? I assume you have done everything from the cognitive therapy angle to work on insomnia.
I know it’s not a popular opinion but I take Ativan nightly and my psychiatrist is totally fine with it. I have cut down from higher doses and I also split the pills and did it very slowly (like 25 mg reduction over 6 weeks). It’s hard and it helps me to have a different meds that help sleep.

Good luck and I hope you’re sleeping better.

You're overly worried about going to a relatively minor lower dose of the Ativan and besides, you've only been on it for 5 weeks, which is a really short time as well. Ativan is not that potent unless you are on the multiple milligram dosages, and that does not apply to you. So what are you going to take instead, seeing as how you have severe insomnia? Ever try melatonin? Your practitioner says it is ok, so just take that for what it is worth. There is a lot of misleading info about taking benzos, but many, many people rely on them, taking them for years and years. The side effects only arise when you want to wean off the benzos and them it must be slow.
