I had Delta/covid last August and even with vaccinations got really ill. Never went to hospital but had to use nebulizer as my Sats we in high 80’s low 90’s for weeks. (Collapsed lung) but had to ask for the xray. Lots of other symptoms as mentioned in these posts but the most debilitating is Insomnia. So sick, so fatigued could Not sleep was Wakeful ALL THE TIME. Cat napped, for weeks and weeks. Now 8 months out I get about 4 -5 hrs average ( not all together). Sleep study, cpap, RLS meds. Meditation apps massage melatonin. Only using bed for sleep yada yada. I fall asleepand boing, wake up, 3-4 hrs later and am Wide awake. Try to sleep. Or get io and read the paper. Do not nap during the day so I can sleep at night. Even went to an “ insomnia” specialist, nada!! Anyone try acupuncture?
