Weed only works once a day for me?

I don't know how else to describe it. I'll start vaping, there's like 20-30 minutes of comeup, 5-30 minutes of euphoria, then everything just feels dull? like hazy and blah. If I vape less, there's less of the 'blah' feeling, but then reality feels harsh and stark.

i get the same thing with edibles generally, 1h comeup, 30-60 minutes of bliss, then 2-3 hrs of gray

anyone experience this; any help?
