My first week on low‑dose rapamycin – sleep and energy?

Posted by greg208 in Longevity & Anti-Aging - 4 points, 6 comments.

I started a pulsed rapamycin cycle last month, taking 4 mg once a week as a retuned firefighter now into my old age. For me the first week was a mixed bag. On the day I took it I had a sour mouth and my hands felt a bit gritty – I think it’s the mouth sores the docs warned about.

I didn’t feel a big drop in energy the next day, but by the end of the week I was more alert in the second half of the day, and my sleep became steadier. I used to wake up every hour with that groggy fog, but after the pill my REM seemed deeper – I recall a vivid dream that lasted minutes, which is a new experience for me. I’d love to hear if anyone else is doing the same dosing schedule and what they notice about immune markers or vaccine responses.

I know the half‑life is about 62 hours, so I wonder how this fits in with my workout routine. Any practical tips would be appreciated.

  • grace_sleepnerd: I’ve just started a low‑dose rapamycin loop myself, 2 mg once a week, and I can relate to the mixed first‑week vibe. I got a dry mouth and a bit of a gritty feel in my hands, so I’m guessing the early side effects you mentioned. About energy, I noticed a subtle lift in the late afternoon, which made my evening training feel less sluggish. The sleep steadiness is something I heard others say, so hopefully that’s a real effect. If you’re tracking TYRA or anti‑viral IgG after vaccination, keep a l
  • liam_sleepnerd: Sounds about right. I got a similar dry‑mouth hit on day one and a bit of hand tingling that faded after a few days. My own late‑afternoon lift was only a few minutes, but it made the last part of my workout feel less laggy. Did you notice any change in HRV or sleep latency?
  • hank_m: I can totally relate, tbh the gritty hands and dry mouth were right on point for me too, i doubled that early relief in the late afternoon, so the training felt a bit sharper, especially after a sip of water or a sugar‑free gum, idk what you do to chase that dryness. Keep an eye on the REM, i noticed more vivid dreams after a couple of weeks, maybe you’ll see the same pattern.
  • greg208: Glad you’re seeing the gritty hand thing, that’s a common first‑week sign. I’ll try a sugar‑free gum next time and keep a water bottle handy to see if that cuts the dryness. I’ve noticed the REM improvement mainly in the first couple weeks, not a whole lot after that, so I’ll keep an eye on it. What brand of gum do you use, and does it feel more soothing?
  • greg208: Thanks, that matches what I felt – the dry mouth and hand tingling did fade after a few days. The short late‑afternoon lift didn’t feel as laggy, which was a relief. I didn’t log HRV, but my sleep onset was quicker – usually 30‑to‑45 min, now about 15‑20 min. Do you think the earlier wake‑ups could be linked to the drug’s influence on cortisol or something similar?
  • greg208: Cheers for the reply, mate. Gutted I’m on 4mg vs your 2mg, might be why my gritty hands lasted longer. Your bit about late afternoon lift matches mine, reckon that’s the punch. I’m not tracking IgG yet, but y’heard vaccines play a role? Wonder if you’ve noticed any immune perks or if it’s all in the head? Also, did your light workout on injection days help or hinder your progress?
