I sincerely apologize for my bad wording and bad punctuation.
My phrase "as Steerpike58 said he planned to do" was meant to refer merely to your "considering requesting other similar meds." I did not mean in any way to imply thay you planned on hiding anything from your doctor. I was explaining to RogerSC why a history of thought-impairment from similar meds would, according to my understanding of the document I referenced, be a behavioral issue any prescribing clinician would want to be aware of, and especially so in the context of a sleep study.
It is always a tradeoff-judgement-call to have someone without a history such as yours to take any med before a sleep study that is not usually taken, but someone with a history of such meds making them get caught in a loop in a way that impairs sleep would especially want to make that known for reasons of safety and to preserve the usefulness of the test involving what should be, to the extent possible, a typical night of sleep.
Please accept my sincere apology. My bad.
I will edit my previous post if you want me to.
