Based on the thread title. Coffee produce "euphoria feeling" (mood changing) for about 15-30 minutes. But it have side effects, witch is you will become stress and depression after 4-5 hours of drinking. Worst, panic attack. The only drink that I know can produce euphoria, is kratom. Small glass of drink, you'll feel euphoria and relax for about 5-6 hours! With almost zero side effects. Plus kratom contain antioxidants that is good for your immune system. But in my country, kratom have been banned by gov. It's illegal now, due to youngster mix the kratom with coke and tend to overdose it, just to feel the opium feeling. If kratom is legal in my country, I think I will drink 1 glass (small) everyday instead of become caffeine/coffee addicted witch is worse. Because old people drink / chew kratom leaf for energy, for them to work in the farm. In U.S.A kratom is legal.
