If your prescriber has asked you to alternate sides week to week, the question that quietly gets harder is which side you actually used last time. One week is easy to remember. Four weeks in, the memory is unreliable.
Eight weeks in, you're guessing. A guess that happens to be wrong is annoying — you wanted to alternate, the point of alternating is the routine itself, and breaking the routine on a Tuesday because you couldn't remember Sunday's choice undoes the whole habit. The fix is one letter.
Pick a shorthand — L for left, R for right, or whatever maps to the rotation your prescriber suggested — and stick it on every weekly entry next to the dose log. Doesn't matter if it's a boring week. The point of the tag isn't to flag anything dramatic; it's to make the alternation legible across months.
Two practical notes. One: write the rule down somewhere on the first entry — a single line that says 'rotation pattern: L / R alternating, prescriber instruction April 2026'. Future-you will thank past-you for the context when the routine shifts and you can't remember which way round it used to run.

Two: don't try to remember without writing it down. The brain is bad at distinguishing 'last week' from 'three weeks ago' on something this small, and the certainty you feel about which side you used last Tuesday is the most common kind of wrong. Titra has a tag field on every weekly entry; one letter, two taps, and the alternation runs itself across the year.
Organisational note, not a medical instruction — the rotation pattern is your prescriber's call.
