Sleep drunk(?)

So whenever I would take antidepressants I would end up feeling kind of similar to drunk. Confused, couldn’t comprehend much very quickly. Tunnel vision almost as well as other things. I haven’t been on any in a few years but I’m noticing the feeling now even when I don’t drink or take any kind of “mind altering” medicine. If I sleep too little, it’s like I’m drunk for a week or more. Always in a state of confusion or disassociation almost. And if I sleep too much, it’s the same. But it’s not all the time. I googled it and got “sleep drunk” but people only have it within the first 20 mins of being awake. I have it for WEEKS at a time. But I’ll be normal for weeks after. Am I crazy ? This just started this year. Is this a real thing that others experience?
