Took a .25 ativan around 3pm. is it safe for me to take my lunesta 3mg? its been 7 hours. cant sleep. still trying to practice healthy sleeping pattern. still getting used to it?

Issue here is a not uncommon tolerance problem with multiple sleep inducing medications. This eventuates with profound sleep pattern disruption. You need to contact your doctor and get more familiar with a sleep hygiene program, and give it time. The medications are best slowly titrated off over a few weeks. Not easy but your best pathway in the end.
