Hey roger, just seeing this. Sounds like you were able to find something that works fairly well -- if you still have questions though, lemme know.
Harris Communications is a good one-stop for this sort of technology:
Sozlet hears just fine but has historically been a major pain in the ass to wake up in the morning. Major. Successful awakenings usually involved dragging her to a sitting position -- she just couldn't wake up while horizontal.
It wasn't about how much sleep she gets either, once she's UP she's bright-eyed and bushy-tailed for the rest of the day. (Well, about 20 minutes after she's up.) And she's just as difficult to awaken after 10 hours as 8.
I'm the same way, I just have trained myself to summon a wave of willpower to get me from horizontal to vertical. Then I'm OK.
We tried alarms for her, they just bleated ineffectually and didn't change anything.
Then, about a year ago, we tried my old bedshaker alarm.
Halleluiah, clouds parting, rays of golden sunshine, etc. It works SO well. It cuts the stress of school mornings by about 90%.
However, my old alarm (more than 20 years old?) started misfiring after a few months of renewed use. It would go off randomly, including at like 3 in the morning. That wasn't good.
Just got a new one a bit ago, all is well again.
I'm very grateful to it and its wondrous awakening properties.
