Based on reports from:
Tolerance
Build-up
develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
Reset
weeks to months depending on half-life and duration of use; taper recommended
Tolerance Decay
Full tolerance
7d
Half tolerance
7d
Baseline
~30d
Tolerance builds quickly with repeated daily use; many users report marked loss of effect within 1–2 weeks and rapid escalation of dose. Conservative spacing (several days to weeks) between uses reduces accumulation and tolerance. Data are largely anecdotal.
