Hi, I was diagnosed as prediabetic in February with a blood level of 55. I managed to lower it to 41 in three months. I've been following a low carb/ sugar diet and have been feeling well and lost weight too. But since I had my booster on Saturday I've been feeling like I was before my diagnosis, shaky, peeing more and generally off. My first two jabs were AZ and I had no after effects but my booster was Pfizer and has made me feel iffy to say the least. I was wondering if anyone else has experienced anything similar and if so what they would suggest I do? I'm still keeping to a sensible diet so know that it's not diet related. I've googled it,like you do and it seems it can affect your blood sugar levels but am wondering if this is just a temporary blip or a more permanent thing. Any advice greatly appreciated.
