GoodRX is always worth checking out, a ton of manufacturers will have coupons if you have insurance but they won't cover it.

Ask your doctor about them, look them up in your insurance's formulary to see what's required (e.g. if you have tried both Ambien and Trazadone and can document it), and see what they can do, before writing it off!

The expectation is Belsomra will lose its patent in 2029 and then generic makers can try to get one approved - so it's not that far off!
