(I’ll start with bashing you, but then I’ll make a U turn, so keep reading.)
If I was you, I’d rather start making incremental changes over a long period of time. “Charging like a bull” never worked in my experience (be it diet changes, exercise, kicking bad habits or what have you), and almost never worked as far as I can tell from watching other people. However, incremental changes made at a slow but relentless pace over a long time (months, years) are not easily undone by temporary failures and, instead, build solid habits that last a lifetime.
“Lifetime” is the keyword here. There’s a nasty pervasive mistake in the current public opinion that makes people do crazy things such as “exercise and diet for 3 months to get into bikini shape for summer” or stuff like that. If they make any change at all, it’s probably due to good genetics, and it disappears as soon as their will power runs out of batteries - which almost always happens sooner rather than later.
Whereas, in real life, nothing works except changes that you make forever. If you make changes to your diet, exercise, etc that you can sustain for 20 years, you WILL see results, and those results will not vanish at the slightest hesitation.
With that being said, hey, the mind is a powerful thing. And nobody is the owner of ultimate knowledge. You’re clearly too determined at this point to change your resolution, so in this case I can only wish you good luck and prove everyone wrong, including myself.
Keep posting.
