It sounds like reality checks are not for you. Its not for me either, so what i did was instead of reality checking i practice ADA(All Day Awareness). This technique is a great substitute for reality checking and has a high success rate. Search up king yoshi's tutorial on ADA, as he can explain it better than i can. You basically pay close attention to your surroundings and the small aspects of your daily life, thus increasing awareness, and this habit will carry over to your dreams.

If you really want to do reality checks however, I would practice one reality check such as plugging your nose and trying to breath at least 10 times a day spread throughout the day. :p
