epithalon nightly drowsiness and injection‑site itch – my 12‑day run

Posted by greg_codes in Safety & Side Effects - 2 points, 0 comments.

5 mg subcut daily for 12 days. wanted to see if sleep quality shifted, so I hooked my ring to track stages and HRV. first three nights were fine, but around day 4 i felt a noticeable dip in morning alertness – like a “hangover” of drowsiness that lasted until mid‑afternoon.

HRV actually went up a bit (around 8 ms higher), but my REM proportion dropped from 22 % to about 16 %. injection sites on my abdomen got a mild itchy patch after each dose, looked like a tiny rash but cleared within an hour. i tried rotating spots and using a cold pack pre‑injection; itch lessened but the drowsiness persisted for the rest of the cycle.

stopped after day 12, and by day 2 post‑stop the drowsiness was gone and sleep timing normalized. just my own experience, could be placebo or circadian shift, but thought it worth posting for anyone tracking side effects.
