Hi @traxsubliminals,
+a few other comments on Patreon and YouTube show that it wouldn’t be a problem to loop it overnight. I too use it as a temporary cure during seasonal changes and loop it 4-5 times for a few days.
More generally, whenever in doubt: the self-monitoring principle (often mentioned on the forum) applies. Perso, I use a big amount of fields but always add them one by one.
After having checked if Dreamweaver has prescribed any minimum/maximum amount and the details in his descriptions + also when these are not available at all:
Generally I simply play the field 2 times (while being awake) and then stop listening anything, in order to check myself for some time. This can vary between a few hours - a whole day. If everything’s fine (which has always been the case for me so far, except for the Sun track but it’s the Sun, after all lol), I drop the field in my night stack.
