When I had insomnia I tried every folk remedy I could find and just like for you it only work on the first tries and then it stopped working and I had to look for the next method eventually I just went to the doctor and got meds, took them for a while and slept like a log best sleep I’ve ever had in my life then sometimes I forgot to take it and still slept well (tho not as soundly) and then one day the meds ran out and I simply forgot to get a refill, never had insomnia again after that, been sleeping well without meds for about 4 years now.
I hope you find your fix (๑•ㅂ•)و✧

i also have insomnia. its a wonder how i can function with just 2-3 hrs sleep. well my patience and mood are worst. i know how it feels and desperate to sleep well but i never think about sleeping around. i also tried several things but all of it works for just few times. one time i watched porn with real humans and i got knocked out in less than 5 min lol but i dont want to do it again fearing the video still plays and my family sees it while im in dreamland.
