I would humbly suggest taking on kabalos which are required, as we all have nisyonos in one mitzvah or another. Whether it’s shmiras aynayim, shmiras halashon, bitul Torah, or whatever else; I think mitzvos which are obligatory should come before deprival of pleasure.
Also, if you learn/daven better after having desert or if you listen to music, I’m pretty sure it’s more important to learn and daven better than to give up those pleasures.
I don’t mean to criticize what is clearly a very meaningful, inspired feeling that people have now, to do better, to be nosei b’ohl. Just some “food” for thought
