I can recommend green tea. It has also a waking effect but not as strong as coffe and in my experience longer lasting. It is more subtle. There are many green teas with different tastes and you have to infuse them the right way. Worth noting is that you should not use teabag green tea but loose one. The teabag tea usually has a bad quality. If you infuse green tea you should not do it too long (usually about 1,5min) and the water should be lower than 80°C. You need to experiment there a bit to find your perfect timings. TLDR Green tea is worth a try, just don't use a cheap one (avoid teabags).
