Do you actually feel the effect of the caffeine in tea?

I’ve been trying to drink less coffee because of GI issues, I’ve been drinking black tea but it doesn’t hit the same way coffee does😐 Does it work for y’all? Any reccs? I’ve been drinking the biglow vanilla chai with black tea.

Edit:

Thank you for all your suggestions. Today I tried brewing one cup of 3 tea bags and steeped them for longer and kept them in there after adding a little milk to cool the tea down. def worked better and kept me up for my work day. I’m going to try all the suggestions, especially pureh and Yerba mate. I’ve tried matcha and I love the taste but also def does not give me any energy boosts. Not sure if it’s the brand or the way I prepare it.
