Same case here. Had Pfizer last 18 Feb and to date, have not managed to get it down to my normal 7s before the vaccine. Just talked to my GP about it but it was a frustrating chat because she didn't think the vaccine had anything to do with it with the 10-minute window, I didn't have enough time to give her a full picture. I'm fee up with the constant thirst I feel even with just eating less than a handful of roasted peanuts. Consolation is she said no one is going to force me have second jab if I don't want it. But still...you'd wish they have time to read this thread so they will understand what it's really like, and that we're not (or I'm not) fretting over nothing.
