I totally understand that, I often forget to actually use the strategy lol

Timer is not the same thing as alarm. I have a physical timer that is also a clock and has big numbers, I place it in front of me so it reminds me time is running. It works for me because I start it myself, it gives me a sense of urgency and I see it as a challenge :D

I bought a timer just for this reason :D It really helps. I think it's good to have a physical one, instead of using your phone - too many distractions there.
