11:00 Took half a tablet of Vit B. Feeling alert so I start studying.
1:00 Feeling tired now. Take a full capsule of Rhodiola. I start feeling effect after 15 minutes.
3:00 Still feel alert
6:00 Still feel alert
9:00 Feeling sluggist. Not sure if it’s because of my dinner or if the Rhodiola is wearing off.
