I stopped consuming energy drinks with caffeine for the sake of Allah. It is my 5th day without it. I didn’t feel or have drops for the last few days so I drunk half a cup of tea yesterday, today I felt the drops again. This leads me to belive that all amounts of caffeine leads to drops. What should I do sheikh, quit all caffeine or can I drink drink as long as I preform istibraa?

While you are certain that what is coming out of you is urine, istibra has no value, as istibra is useful in case of suspected wetness.
Accordingly, if consuming these drinks leads to your inability to control urine, stop them and trust that you will not be harmed by this, but rather your health will be better, for what you eat destroys your health.
