well, i am about a 25 year vet dealing with adhd and bipolar i dont want to go on but important, chronic insomnia i used to drink heavily and i used to say to my pdoc that i liked the alcohol hangovers they grounded me and brought me down to earth. Now i dont drink maybe the odd 2 or 3 beers every 2 months, i take clopixol which mixes well with all my other meds and lets me sleep and i wake up down to earth. Getting to my point i read an article recently about foods, it was saying " i take my meds same time every night and same meds why do i get hangovers on only odd days" im sorry i cant provide you with the link i forgotten it. Look into your diet and see if eating before meds or long before meds makes a difference. My pdoc couldnt get me to sleep and retired after 20 years with the only thing that got me to sleep was thorazine 1g, but my md prescribed clopixol which with my diet gets me to sleep but some days im getting heavy hangovers, this is when it works. its a shame my pdoc never found out clopixol works for me, i have a routine with down time before sleep. I'm looking into my diet and sleep and hangovers right now and keeping records. sorry i cant find the article for you but maybe its a place to start. My meds are much stronger on an empty stomach and a worse hangover. on a full stomach they tend not to work and i wait 2 hours and take 10 more mg and dont get a hangover.Its interesting. Hope this thoughts make some sense.
