God damn is sarcasm so fucking hard for you? You are obviously having a real struggle here. Diabetes can cause brain fog, characterized by memory lapses, reduced focus, and mental sluggishness. This is driven by unstable blood sugar levels (both high and low), insulin resistance, and long-term damage to blood vessels in the brain. Managing glucose levels through diet, exercise, and medication can help reduce these symptoms. Do you need your doctor to increase your dose?
