Is a baseline blood test really necessary before starting something like this? Tolerance was my main issue with citicoline too.

What is the first thing you would read if you were starting from zero?

How do you tell the difference between the drug working and just a good week? Six weeks in on a shortage and it lines up.

How do you get a clear photo of an imprint? Mine keep coming out blurry.

Sorry for the basic question, but how do you actually start one of these diaries?
