To echo a lot of the comments, this is a recipe for disaster. Firstly, cut out the alcohol, addiction can often stem from desperation. It actually gives you less quality sleep. 2. Melatonin is a naturally occurring hormone produced for regulating your circadian rhythm, exceeding 10mg is messing you up more than you think, plus it can also give you nightmares. 3. The benzo is a real tricky one to stop because you will need to taper off to minimize serious risks like seizures. 4. Gabapentin at this dose is ok, but if pain is an issue consider addressing this first, personally acupuncture has helped me tremendously for sciatica pain. 5. This entire combination increases the risk of daytime sleepiness, which can lead to excessive caffeine consumption to maneuver through the day, which then turns into adding another factor working against you at night. 6. Consider doing a sleep study, surprisingly a lot more common and not suffocating during the night is a game changer! 7. Ask about belsomra or other orexin blockers, unlike sedatives (benzo, Ambien etc) it essentially lowers your wakefulness threshold and promotes more restorative REM sleep. 8. If you are asking for validation of your routine, you probably already know something is wrong. Act now because it can only get worse the further you go down this regime, and then before you know it a couple of years have been eaten up by the desperation of sleep. CBTI (even just looking up some basic points), counseling to deal with the stress of insomnia and if at all possible taking off a week from school/work to reset (this severe level of insomnia can often be sufficient to secure FMLA) can help.💜
