NOT PROUD, more embarrassed and don't even really wanna write out this story, but I wanna help and on this forum I don't hide anything. I feel we are all family.
I went 10 days without sleep (no you don't believe that, no one does it's fine) this was confirmed after an A&E stay in Northwick Park, Harrow, by all means ask them, record for them. 11 days is the world record, by no means trying to look 'cool' it's hell. I tried to knock myself out after 10 days with loads of downers and sleeping tablets, I OD'd ended up in hospital. Extreme, don't do this. You've no idea how much agony the body takes after it (neither did I)..
Anyway. Moved country to recover, found a GP who actually cared and was shocked by the whole situation (unlike my previous GP who did not care) so he rang the A&E to see if I was talking rubbish. I wasn't, next week got me in and did 8 full things of bloods, I have an A4 page font 8 with nearly everything you can do (done twice 3 months apart, ouch) .......apart from vitamins for some reason, it's online if anyone really wants to see for sure, anyway long story short...
My bloods were all over the show, he sent me to an ENDO and after a synacthen test it turns out my adrenal glands were/are over worked and I lack Cortisol so it sends adrenaline around my body.
Do what you can to get a full hormone profile. I am not talking 1 bottle of blood and some little test. I had this many times showed nothing, you need the full thing. Honestly.
For me it was Adrenal Glands. I'm not saying this is your problem but hormones in sleep are MASSIVE. I had Zoplicolones over 100 in one year, way illegal, 25 I was told by my new GP in a year is the limit, but my old doctor obviously could not find anything and was at a loss after trying Meltalonin, Ambien, Lithium, Seroquel, Diazepam, Mirtazapine, got diagnosed as Bipolar... the whole 9 yards...after a lot of drugs my ENDO said.... this is not a mental issue. Turns out hormones are more powerful than I ever imagined... and a lot of doctors.
Basically, search deeper. Also adrenaline is easy to spot, see if your eyes dilate bigger at 10pm ish, the first thing I noticed was my eyes looking like owls eyes. I'm not at the end of my story, but I learnt recently... stress causes hormonal changes. Get them ruled out, they can be fixed.
TLDR..... Hormones are more powerful than you can imagine, get a full test and get that ruled out first or you might be attempting this from the wrong angle. When you have depression and anxiety a lot of things get over taxed
Also don't believe private 'full tests'. I paid 500 pounds in harley street to do a hormone test... that came back normal with about 10 things on it, this is no where near the list i can show you now as a real hormone profile.
Obviously this is not easy to get, so if you can't, from what I know about Hormones (not that much) Testosterone, Prolactin, Cortisol are musts. A lot of doctors don't understand the importance of Cortisol, it was missed for 10 months of searching. I'm sure someone else can add more weight to what hormones are important that relates to sleep but if tablets can't make you sleep as I said, it doesn't have to be in the head...
