specific overdrive question

In light of the other message, I was wondering if engaging and disengaging
overdrive somewhat constantly is bad for the tranny. I am not talking about
doing this after in overdrive, but before hand, like in 3rd gear. There are
some times when I'll feel that i'm about to go into overdrive, but maybe
ten seconds further up the road there is a turn i'll need to slow down for.
Meanwhile right after that turn I may be able to go 60 easily so if I leave
it disengaged the entire time, i'll get real bad gas mileage because of
fast stretches but at the same time if it's engaged, that's extra shifting
creating the heat.

Also, for going on to highways where a quick speed up is needed, is it
suggested that o/d be turned off until i've reached the speed limit, or
close to it so the truck doesn't do so much down shifting?

Any help is appreciated.

Thanks!
