My boyfriend took like 7 mg or more of klonopin

And an unknown amount of sudafed in one sitting, (i think st least a few tablets) and idk if he took any other meds or not... this was in the middle of the night, he was slurring his words after and seemed out of it, then i told him to lay down and he fell asleep. he’s been sleeping now since 5 am and it’s 9:30 now. and he isn’t waking up to me moving around or the dogs barking like he normally does. I can hear him snoring..

i did some research and it seems like he’ll be fine, but like i just don’t really know what to do, do i try to wake him to see if he’s able to be woken up? or just let him sleep indefinitely...?? he can sleep up to 12 hrs even with no drugs sooo at what point do i start getting concerned
