Where you live is hotter than where I live. Here the temperature is usually around 40 °C, and especially at Easter time it reaches 43 or 45 °C, I understand why you need to drink a lot of water and stay hydrated. Water with lemon juice is really beneficial, because it alkalizes the human body, making it more resistant to infections. I haven't had the pleasure of drinking methi water and periwinkle flower tea, but they sure are very tasty.
Thank you for participating in the contest.
