I have always been quite fond of the entire benzo family but last summer a friend gave me a bag of 5mg librium caps and I fell in love. Librium is much more subtle than Valium or Xanax and I think that might be one of its biggest atributes. I can take one pill and it mellows me out but I am still quite functional.

Summary
Chlordiazepoxide was the first benzodiazepine synthesized and is primarily prescribed for anxiety disorders and acute alcohol withdrawal. It has a long half-life and produces long-lasting active metabolites, making it useful for tapering but inappropriate for elderly patients due to accumulation risk. Abrupt discontinuation after prolonged use can cause life-threatening withdrawal including seizures.

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
14d
Half tolerance
14d
Baseline
~42d
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Benzodiazepine tolerance builds to sedative/anxiolytic effects within days to weeks of regular use and decays slowly over weeks after cessation. Cross‑tolerance within GABA-A positive modulators is substantial but incomplete; individual variability is large. Data derived from clinical guidance and community reports; figures are illustrative, not prescriptive.

Well after already going through the DT's from Alcohol withdrawal all by myself and with the help of my Ativan and Trazadone prescription....my counselor suggested I go ahead and go into detox anyway.
I received a supply of librium from a foreign pharmacy. The pills were encased in foil. Upon removing them I notice they had no marking, but I took a sample dose to make sure they were what they said they were. After consuming 75mg, 00:30+ Mild Sedation, a general relaxation.
first time I took the capsule at around 4:30 this afternoon and it left me in a rather good state. Nothing out of the ordinary, I just felt alright...no negative thoughts or that antsy feeling that I just can't seem to shake off sometimes.
I have experience using Librium, or generic Chlordiazepoxide for detox setting in inpatient treatment centers to detox off severe alcohol dependency and even somewhat of recreation. For context, I have experience using every substance in the book, minus some of the newer noids, and Research chemicals available now.
I have been taking ~0.75mg Xanax twice daily for about 2.5 years now, it helps alot with my general and social anxiety. My dodctor suggested switching to Librium as it is longer acting with less 'addiction' potential. This morning I woke up and everything felt like a normal day, mentally and otherwise.
From 19 to 23 I was quite a hard core alcoholic and weed smoker. Could never quite get away from it, I suppose I was just self medicating for depression and general anxiety.
I was expecting to feel euphoria after reading other experiences. I am tense from a general addiction to any drug but I am in a relaxed environment. I take Mirtazapine and Paxil for depression, and I smoke low-grade marijuana at all times.
