"belsomra offers a voucher for free (10 days of 10mg, 10 days of 15mg and 10 days of 20mg) so i tried them all and now i am going to use the voucher for $3 ($90 a month) a pill if your insurance requires a payment of more than $150 and $1 ($30 a month) a pill if insurance requires a payment of less than $150 since i haven&#039;t met my deductible.   i was just visiting this site to see how long it takes for the dosage to level off since i am feeling a little drowsy on the 20mg. so if you need to try it to save a little money use the vouchers.  i love this pill since i was taking amitriptyline before and was always so exhausted the next day.  i think i will try the 20mg for the month and back down to the 15mg if i am exhausted by the next refill"
