My 8‑week trial of CagriSema: appetite dip, nausea spikes, and a weird HRV bump

Posted by amber464 in Weight Loss & Metabolic - 10 points, 4 comments.

I started the fixed‑ratio CagriSema combo about six weeks ago after reading a few threads on dual‑pathway GLP‑1/amylin mixes. My protocol was the starter pack: 2.4 mg semaglutide + 2.4 mg cagrilintide once a week, injected on Mondays. I kept my usual diet (about 1800 kcal) and logged everything in my spreadsheet – weight, waist, fasting glucose, daily steps, and nightly HRV from my Oura.

First week I felt a mild nausea that peaked around day 3 and cleared by day 5. Appetite was noticeably lower – I was eating roughly 300 kcal less without feeling “starved”. Weight dropped 3.2 lb by the end of week two, mostly water. My HRV rose about 7 ms compared to baseline, which I think might be linked to the reduced post‑prandial insulin spikes.

By week five the nausea returned on injection days, but only for a few hours. I’m still seeing a steady 0.8 lb per week loss, and my waist is down 1.5 inches. No injection site irritation so far. Anyone else see the HRV bump or have tips for taming the repeat nausea?

  • aspiring_codes: I tried a low‑dose Cagri‑Sema combo a few months back for similar weight goals. I also got a modest HRV lift – about 5 ms – which I think was just the calmer overnight glucose and less sympathetic “food‑fight” vibe. For the nausea, I found taking a tiny chewable ginger tablet about 30 min before the injection helped smooth it out, and staying well‑hydrated (a glass of water with a pinch of salt) right after the shot reduced the queasy spikes. Anyone else play with timing meals around the Monday
  • amber464: Thanksfor the tip I tried a chewable ginger tablet 30 min before my Monday shot this week and the queasy spike was noticeably softer, plus I chugged a glass of water with a pinch of salt right after. I’ve also been pushing my dinner to earlier in the day on dose days – seems to blunt the nausea and keeps my HRV steady around that 7 ms bump. Did you notice any change in your overnight glucose when you added the ginger?
  • chemist_daily: fwiw I also tried a small ginger chew about half an hour before my Monday Cagri‑Sema shot and it did take the edge off the nausea for me. I noticed a similar 4‑6 ms HRV rise, which felt like calmer nights after the appetite dip. Have you found eating a light protein snack right after the injection helps keep the queasy feeling at bay? ⚡
  • amber464: Glad that ginger worked for you, I tried it once around day 3 and the nausea fizzled faster, but I didn’t pair it with a snack. I’ve been eating my regular 1800‑kcal meals after injections, so I’m curious. I’ll add a 20‑g whey shake or a turkey slice the next Monday and/sec log HRV. What snack did you use?
