One thing I noticed after reading different user experiences in Australia is that everyone reacts a bit differently to Modalert and Waklert. Some people say it helps them stay productive all day, while others mainly notice better concentration for a few hours.

A lot of random questions usually come up around food, coffee, sleep and timing. For me personally, taking it with too much caffeine just made me feel restless instead of productive.

Artvigil felt smoother during long work sessions, while Modvigil felt lighter overall. Most users seem to agree that it works best when used occasionally and not as a replacement for proper sleep or rest.
