I searched through old threads, but couldn't find a straight answer to this question. If I take Tylenol tonight to keep me asleep, would that affect BBT in the morning (since it will have likely worn off)? Anyone have experience with this?
I don't see why it would, however make a note in FF just in case later on tonight's temp seems odd. You'll know in a month
Fwiw, I've took Tylenol and not had an issue, but everyone is different.
Thanks for the insight. I could potentially see it lowering BBT too much if taken within the 6 hour window or so, I was just wondering in general.
Yes, I would just make a note of it in your chart, and after a few days, if that temp seems like a big outlier, you could discard it.

The half-life of Tylenol is short (about 2.5 hours), so most of it should be out of your system after about 7.5 hrs. (Technically, it's not completely out of your system until 5 half-lives, but 3 should be close enough for temping purposes.)
I would still mark it in your FF chart though in case that temp looks off comparatively.
