Yes, I have the same problem and I'm so glad to read I'm not alone on this as my drs keep rejecting the idea that my sudden out of the roof blood sugar might be related to the vaccine I have received back in July. Prior to the vaccine I have been keeping away from medication and sometimes I could even lower to 4.7 and 7.5. I've diabetes type 2 and diagnosed about 14/15 years ago.
Since the vaccine, there is no way my blood sugar will drop from 12. I'm now taking Metformin but, funnily enough, after eating almost to nothing, more sensibly, walking about 7 miles and having taken the Metformin, my blood sugar goes and rises! today, from 12.5 before eating breakfast and taking metformin to 14.4 after 3 hours and walking between 6 to 7 miles.
some days being without food for almost 16 hours, I had 20.8.
I am delaying the second dose until I have answers instead of my Drs saying its got nothing to do with the vaccine. I've lost all trust since they don't even know but insist it isn't related to vaccine.
Mine was Pfizer. I don't know what to do anymore.
