Abt switch

The Abt switch is a kind of railway switch used on funiculars (inclined cable railways) that doesn’t have any moving parts. It allows two cars to pass each other going uphill/downhill while sharing the same tracks. While most train switches rely on physically moving a section of track so the train goes one way or the other, the abt switch doesn’t move at all. Instead each carriage has a grooved wheel which makes it turn left or right at a junction by sticking to the track on one side.

    Third injection done, end of week 2. Air bubbles are a pita. I think I can draw more then my dose and push it back into the vial though? So it ends up working out.

    Cried more then usual this week, more tears, other then that nothing to report. Injection also hurt less then last time so maybe I just got unlucky and hit a nerve or something.

      Thats what I do at work and for myself. I always draw more than I need and push up the remainder and any bubbles out the needle and measure out exactly with the needle amd syringe full after. For myself only (I dont do this at work unless its prefilled) I do use a bubble at the very top of the injection to push ALLL the E in. I wouldnt recommend it necessarily because if you do it wrong you are creating subq emphysema but also… really I dont think its a big deal and just a bit of mindfulness during the injection would catch it.

      I think you’ll be feeling the low dose antidepressant soon~ a few weeks of crying way more than youre used to and I think in the next week or the week following you’ll notice things aren’t quite as hard as they used to be and things dont hurt as much (they still might but more easilt).

      draw double and some of your dose and then push it out into the vial to your dose, should deal with any air bubbles (and any left will be too small to be significant) (not that they really are significant tho ppl have anecdotaly reported more pain)

          with the different viscosity of oil etc it looks like a llt more in the end

          i switched from im to subq and despite now experiencing what looks like a significant amount of leakage in reality my levels are the exact same :3

          if you have a large enough air bubble yes itll mess with dosage, but at that point its not an air bubble more just… space that wasnt filled

            Oh damn, I haven’t had anything but (sometimes) the tiniest pin prick of blood imaginable come back out.

            Fair, I’m not sure where the line between air bubble and empty space is tbh ohnoes
