FTFY. Everyone’s brain chemistry is different. For some, it can be a lifesaver in low doses for anxiety, for some (like me) it can be used as an adjunct to acetaminophen/paracetamol in a combination that is more effective for pain than opioids (had a minor hemorrhage in an adrenal gland - not fun), and for others it can cause extreme depression and other behavior changes.
