hello concerned patient, Thanks for writing to HCM. i read your query and understand your concern is regarding the insomnia you have been experiencing for some years now some details would have helped: your age and sex? your occupation and its nature? any medical history/drug history/familial history?? what all medicines has been tried in your case??-u have mentioned 10 different sleeping prescriptions. If i were the doctor treating you,i would advise the following: -avoid stress ,try relaxation techniques,meditation etc. -avoid daytime naps -try to follow a sleeping schedule at night,so that your body syncs up -avoid caffeine -exercise regularly -i have seen inducing behavioural changes through cognitive behavioural therapy to work for many patients and that can be tried if the above doesnt work. - another newer technique is in addition to pleasant climate(not too hot /cold),is a technique of breathing called 4-7-8(please look it up,lengthy to explain here) and listening to soothing white noises like rain drops,small breezes etc which are available as mobile apps. -then take a medication like alprazolam 0.5mg for 10days at night or zolpidem tartrate at night which should give a good sleep when combined with above guidelines in mentioned Hope it works out for you and hope it helps. Let me know how it feels after a fortnight.followup if any doubts. goodday
