For lethargy and reducing eye redness.. Maybe I can suggest, trying high content vit c fruits, such as oranges, mandarins, kiwi, grapefruit, etc. Also, soluble vit c tablets can increase energy.
The fruit effects can take between 10-30 minutes to take effect on these symptoms depending on the strains ingested and amount. Get plenty of fresh air and use deep breaths to flush in the oxygen and out the co2. Try and avoid this for more than a few minutes in order to prevent dizzying.
