I absolutely have!!! Back in 2011 before I got sober. I was terrified of falling asleep too...I won't go into all the details except to say I checked myself in to Psych ward for the weekend at one point and took Seroquel for a year. (I also started hearing music and voices that weren't there (that was only for one day)That wasn't necessary. Turns out it was all due to drinking and withdrawal from alcohol. I believe that the beating myself up and self loathing contributed to it as well. I have been sober for three years now and have had absolutely no symptoms like that ever again.
I feel for you...I remember exactly how it was. Take comfort in that this is most likely "alcohol related". I would also suggest getting to a doctor to help you with the WD process.
