i suggest this but urge you to use caution and research first, I take kratom for anxiety. It is also used to to ease pain and discomfort associated with withdrawing from any substance really. SO it may help you to cut the caffeine out, if you have anxiety and looking for nootropics, caffeine is the last thing your body needs. I know the headaches and fatigue from stopping caffeine can be hard but they don't usually last more than 3-5 days. Good luck! if you don't have chronic pain or anxiety there is no need to use kratom daily. So for easing the withdrawal caffeine , maybe use it for about 3 days max. If you still have a lot of anxiety, kratom is way way way way better for you than what a doctor would give you aka a benzo like klonopin or xanax. I'd urge you to try kratom for anxiety before trying a prescription as they are much more addictive. Kratom can come with withdrawals as well, mostly similar to caffeine withdrawal but without headache- mostly just fatigue or "brain fog", so just a suggestion since you say you are having a hard time stopping the caffeine.
