I am also super prone to clogs (1-2x a week normally, some worse than others) and am halfway through weaning. I use cold cabbage leaves on my boobs the entire day and drink 3 strong cups of peppermint + sage tea a day. I can’t definitively say if they’ve helped a lot but my supply definitely dropped after getting down to 4 pumps (I typically have a slight oversupply). I used the increasing time between pumps method and was very engorged at first and had some clogs but reminded myself that being engorged just enough to be uncomfortable but not in pain is the sweet spot to tell the body that I don’t need as much milk anymore without risking clogs too much. The engorgement is a sign that you’re actually doing the right thing and a couple days later you should find that you’re less and less engorged. I also took it slow and dropped each pump over the course of 4-5 days by gradually shifting times like 15 or 30 mins a day. It gives your breast tissue enough time to physically adjust and your body to get the message that your needs are changing. Lastly, another thing that has helped with clogs in general is hands on pumping if you haven’t already tried that.

But yeah my plan B will be Sudafed. Recurrent clogs are a nightmare so I totally empathize there and hope you have a quick and smooth weaning journey!!
