I think it's important to understand that there are trade-offs, even if this is a very powerful treatment. I tend to vary between THC-assisted sleep anywhere from 25% to 100% of nights and the trade-off of reduced REM is totally worth it. I do find that extended periods of 100% assisted sleep tend to make my memory a little foggy and that taking a week off resets things.

Caveat: anecdote is not data and all that...
