There are a lot of foods and beverages that contain caffeine, so you might find it challenging to avoid it. One of the simplest swaps for caffeine is water, which is hydrating and can help if you have caffeine withdrawal symptoms. If you're used to getting energy from caffeine, you might be tempted to switch to sweet beverages and snacks for a quick boost. However, try to avoid making this your replacement, as sugar can cause crashes and contribute to health concerns over time.
