hello I got diagnoised with type 2 diabetes last year in may and got a cold last week. Been taking the antibiotics my doctor gave me to treat it is it. I also do stuff as I normally would but when I was taking a shower I felt a sudden wave of dizzyness and then a white blurr to my vision for a few seconds before it passed. I also noticed the antibiotic's make my blood sugar go into an eregular state even for me since I have it fairly well controlled with exercise and diet.
