First week on low-dose Metformin – changes to sleep and energy

I started a 500‑mg Metformin daily routine last Friday, mainly for the AMPK activation rumours that keep popping up in the longevity chats. I’m no stranger to the gut side‑effects – a mild, metallic taste at first and a bit of loose motions that settled after a couple of days. The night before I was asleep around 10 pm and woke up feeling oddly refreshed, almost like the sleep was deeper than usual.

I’m still debating if it’s the dose or just catching up on a night off after a long shift in the station. Energy-wise, the first few days were a bit of a roller‑coaster; midday dips were sharper but I found I could push through a tough training session without the usual pre‑workout cocktail. In the evenings I’ve noticed my cravings for carbs are lower, which I guess is a sign that the glucose output is down as the docs say. If you’re thinking of trying it, start at the low end and be ready for that’s‑a‑little‑bad‑mouth‑taste side‑effect.

  • aspiring_trailrun: I’ve been on 500 mg a day for a month now. The first night I got translates to a similar “deep sleep” vibe – I woke around 9 pm feeling more rested, though I think a decent night shift at the station and a shift in my routine played a part. Energy is a bit lower mid‑afternoon, but I’ve been able to finish races without the usual pre‑workout mix, just the usual “hunger dip” about an hour after lunch. I notice the sweet cravings dampen, probably because of the glucose feedback. Funny thing: the m
  • greg208: Nice to hear you’re seeing the same vibe. I’ve got a shift that skews the night‑shift vibe too, so it’s hard to untangle sleep from routine. I’ve yet to try splitting the dose or a light breakfast to curb the metallic taste – that’s on my list. Any idea if it helped you keep the taste under control? Also, how’s your mid‑afternoon dip now after a month?
