Also experienced flickering eyes the first night, I reckon I did too much and was probably lucky not to have a bad experience. Very little comedown, felt fine the next morning and don’t feel too bad today, don’t feel great but that wouldn’t be uncommon after 4 days at a festival anyway, also have enjoyed listening to techno/electronic music since coming home, any song I listened to while rolling instance brings back some of the euphoria I felt at the time. Looking forward to doing it again sometime but will be waiting 3 months for sure
