How to prevent after lunch drowsiness ?
Sin-Full way: take a cup of potent mocha topped with 2 scopes Milo, this is sleep proof and the effect kicks in within minutes.
Double-H way: being healthy and hygienic, avoid meaty heavy lunch, less oil more leafy light meal, follow by 4-mins teeth-brushing and 30-sec oral-rinsing.
Tested and proven effective for the above two(my current practice is the second), welcome any creative and innovative ways, I'll definitely try out!
