Do Antibiotics Affect Blood Sugar Levels?

What can you tell me about probiotics? They have really messed up my ability to control my blood sugar levels. I can feel them crawling inside me when I eat. I go extremely hypglycemic (45) and then jump to 165 from one sip of sweetened almond milk. I suspect it is because the probiotics are eating everything I eat except for sugar since that goes straight to the blood steam. Help, I feel like I am going to die if I can't get this under control. I eat Choboni yogurt and activia. My prenatal also has a probiotic blend in them. I have searched high and low for answers and everyone says you should eat probiotics everyday. I really need answers. Thanks, Alison Hoernemann
