1. Other than driving and operating heavy equipment while listening, what other times should be avoided when listening, Sleep?
2. How often as in daily and how many times a day?1-2, continuous loop?
3. Are subliminal messages more effective in trance? (I would guess yes)

Depends...

(yeah, that pretty much sums it up. I don't recommend listening to anything while you sleep because it tends to ruin your sleep and sleep is good)

I'm really looking for some kind of base guidelines to follow, to avoid over saturation.

For me and for the kind of files I like, it would be once a day or a couple of times if on loop, in the early evening if possible. Oh and trance is the cake, subliminals are just the icing.

Generally if you're getting too much of something or you're getting something you don't like, you will know. You just won't feel like listening... it'll feel uncomfortable. If that happens, slow down. Contradicting suggestions will also have this effect.
