Conclusion: Overall, eszopiclone and lemborexant had a favorable profile, but eszopiclone might cause substantial adverse events and safety data on lemborexant were inconclusive. Doxepin, seltorexant, and zaleplon were well tolerated, but data on efficacy and other important outcomes were scarce and do not allow firm conclusions. Many licensed drugs (including benzodiazepines, daridorexant, suvorexant, and trazodone) can be effective in the acute treatment of insomnia but are associated with poor tolerability, or information about long-term effects is not available. Melatonin, ramelteon, and non-licensed

The short answer. There isn't much data on Doxylamine yet — 29 mentions, 15 with a clear outcome — so treat these numbers as anecdotal. It is most often used for sleep: 86% of 21 reports say that improved. It is well studied — 15 meta-analyses on PubMed. The most common complaint is drowsiness.
From 29 mentions in total — the rest didn't say how it went and aren't counted.

Conclusion: For mild symptoms of nausea and emesis of pregnancy, ginger, pyridoxine, antihistamines, and metoclopramide were associated with greater benefit than placebo. For moderate symptoms, pyridoxine-doxylamine, promethazine, and metoclopramide were associated with greater benefit than placebo. Ondansetron was associated with improvement for a range of symptom severity. Corticosteroids may be associated with benefit in severe cases. Overall the quality of evidence was low.
PubMed 27701665 ↗Conclusion: There was evidence of some improvement in symptoms for some treatments, but these data may not be transferable across disease severities. Methodologically sound and larger trials of the main therapies considered within the UK NHS are needed.
PubMed 27731292 ↗Conclusion: There is a paucity of studies examining pharmacological interventions for sleep and circadian rhythm disturbance in BD. Few studies assessed sleep-related symptoms, and none quantitatively examined endogenous melatonin patterns or other circadian rhythms. Melatonin may be a promising candidate for the adjunctive treatment of bipolar mania. However, dose-finding studies and studies with larger sample sizes are needed to confirm its efficacy. We recommend parallel monitoring of sleep and circadian rhythms in future trials. Chronobiology-informed trial designs are needed to improve the quality of

First-hand experiences, quoted verbatim. We show one positive and one negative where both exist.
“I've been on OTC sleeping pills (e.g. Unisom) ever since. I've tried numerous times to get off but then I'll only get 30 mins to 2 hrs of sleep per night without it.”
“I've tried a bunch of supplements and none of them work to help me stay asleep”
“The best meds for my sleep are THC and surprisingly doxylamine. Out of everything so far, doxylamine is probably the most helpful.”
“unisom works really well for me even though i am aware that its not really a biohack”
