Don't skip meals. If you are prone to low blood sugar episodes, eat 5-6 small meals per day instead of 3 larger ones. Avoid sweets on a regular basis, but carry a quick source of sugar with you at all times, such as a small can of orange juice. This will give you a quick source of sugar in the event that you do get a low blood sugar reaction. Limit or avoid caffeine intake after noon.
Caffeine can worsen anxiety and lead to poor sleeping patterns.
If you must drink coffee, switch to decaffeinated. Also use decaffeinated teas, colas, and other sodas. Limit your intake of chocolate. Avoid nicotine and alcohol. Avoid medicines that have a stimulating effect, which can cause anxietylike symptoms.
