I spent 5 hours painting, my back ached and I did not know if I would return to the job after lunch. Before I ate I took a Rhodiola Rosea Extract tablet. By the time the quick lunch was finished my back ache was gone, and I did 4 more hours of painting. I was dead tired after painting, took another dose, showered, ate and felt refreshed enough to read until 11 P.M. without nodding off as usual. The dosage recommended on the bottle is way too high. Read the linked articles at www.rhodiolarosea.org which mentions a 150 mg dose. Use a pill splitter.
