It would be better to microdose lithium if you really don’t want to be high imo. 5-20mg range, can be intermittent (doses for bipolar are in the 100mg range and up). There’s already lithium in some water supplies and in foods like potatoes, so a small amount in a microdose normally doesn’t affect anyone negatively.
I will say over time your body will adjust to cannabis so if you microdose at night consistently before bed, you’ll just sleep it off anyway and eventually it won’t even get you high anymore.
