advice on sleeping- please help

hi guys

so recently i’ve had really weird nights. it started when i was taking a medicine that caused insomnia so it made me stay up and be exhausted with cold sweats and shivers and throw up. now, i’m off the medicine but i can’t stay asleep for more than 3 hours at a time at home no matter what i do. when i go sleep i have a sort of uneasiness feeling and when i wake up its very sudden and my entire body is tingling. i went away for a few days and slept very well in a hotel but it’s my first night back home and it happened again.

what’s happening and what do i do?

it’s starting to scare me and make my days very hard.

please help
