> Personally I had a very hard time even breathing in then holding my breath for 3~4s (heart pounding, growing panic state), so I found that "anything goes" helped me a lot in achieving 4-7-8, and in turn 4-7-8 helped me a lot in achieving 4s box breathing. Thanks for this. I could 4s box breathing from the start but appreciate that some folks need intermediate steps to ramp up.
