I’m not saying this as a poster on a public forum but I don’t think very many, if any, are actually dropping ambien type meds on the road. It’s got at least a 48 hr limitation as I recall and those kind of meds can cause false positives on random drug screens. I know plenty who use them after a trip, however.
I’ve used melatonin in the past but found it doesn’t really help. Exercise and abstaining from alcohol are the biggest factors for me…and slam clicking on layovers. It sux but often way better on the body to sleep vs committing to arbitrary plans. Careful use of caffeine too.
