I recently realized that having my iced latte around 5pm might be the culprit behind my restless nights. Despite the refreshing taste and the much-needed caffeine boost, the timing is crucial. Caffeine can stay in your system for several hours, affecting your ability to fall asleep later. From my experience, switching to decaf or herbal tea in the late afternoon made a significant difference in my sleep quality. If you love Dunkin's iced latte but struggle with sleep, consider adjusting when or what type of drink you consume in the evening. This small change has helped me enjoy my favorite coffee earlier in the day while ensuring I get a good night’s rest.
