What is the Rov’s opinion about people who make an early Shabbos and then eat without Krias Shema and Sefira? May one be meikel (be lenient) if he puts a paper on his pillow as a reminder?

Poskim agree that when someone accepts an early Shabbos, before the proper time for reading the Shema and counting Sefira, since when starting at a permitted time, one does not have to stop the meal when the correct time for the above arrives. One may just wait until the end of the meal and the reciting of Birchas Hamazon. In order not to forget to read and count, one may ask the proper person present to remind the others. Horav Shlomo Miller’s Shlit’a opinion is that similarly one may place a note or sign in a place where it will be noticed to remember all of the above mitzvos to be done.
