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

Question

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.

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 log – the data is sketchy, but changes can popinkel. For workouts, I keep the session light the day after the pill, maybe a 30‑minute walk or bike, and jump back to full intensity the day after that. That gives the drug a chance to circulate before you hit hard. Any of y’all using a weekly dose with a focus on immunity? Just curious.
