"after being on tamaze for 15 years, i was told i need to go off it, as it is a drug of dependency &amp; dangerous to mix with my pain meds long term. for the next 6 months without it, i was lucky to get 1 solid hr of sleep without waking every 10 minutes &amp; would go for many days with no sleep at all. eventually my doctor said having no sleep is just as bad for me long term &amp; prescribed me belsomra 20mg, as doesn&#039;t have the same chemical make up as most sleeping tablets. even though expensive it has been a life saver for me and when i do lie down, i&#039;m usually asleep for 5 or 6 hours solid. i have many side effects &amp; allergies to most medications, but belsomra has very few side effects, which i have none so far &amp; worth ever $$"
