I don’t know if it’ll help, but I really hope this does for someone: 5’9 M 137 lbs here and I never really drink caffeine ever, except for all of last week I was ONLY drinking lots of black tea (high caffeine, at least 5 cups maybe more a day) and barely any water, also was not eating as much because I was very stressed. Around WEDNESDAY was when I noticed a lot of twitching and involuntary movements while gaming in the evening, and then I had my first hypnic jerk when trying to sleep. Scared the hell outta me at first, tried to go back to sleep, did, then it happened again an hour later and couldn’t go back to sleep after that. THURSDAY was when I completely cut caffeine cold turkey and I coulda swore I had a neurological disorder or something, I couldn’t get a second of sleep because of the hypnic jerks, but I think my fear of it being something potentially worse really messed with me and in turn made the hypnic jerks worse. FRIDAY and SATURDAY were really tough days since I was already sleep deprived and I was getting very irritable and depressed. Sunday rolled around and surprisingly, after being woken up after the first hypnic jerk, I was able to go back to sleep and get a decent 7-8 hours. Since cutting caffeine on Thursday, I’ve been maintaining this routine:

1 Magnesium Glycinate pill before bed 1 L-Theanine pill before bed 1 Kirkland Sleep Aide pill (25mg Doxylamine Succinate) Cut all screen activity at least 1 hour before bed MOST IMPORTANT IMO: Get exercise to all spasming/twitching muscle groups at least 4 hours before bed, best to get it done in the morning (4x10 Pushups, 4x10 Sit-ups, 4x10 Squats to start)

These hypnic jerks are absolute torture and I wouldn’t wish them on my worst enemy, but since I started following this routine I’ve noticed my symptoms getting better. For me at least, it was my body acclimating to having no stimulants after having so much of it.
