Glad you're having a good time. I would wait at least 3 to 4 hours before redosing anything if you are feeling slightly dizzy. Taking a small dose of Benadryl or other sedating antihistamine can help a lot with the dizziness and itchiness and also potentiate your oxycodone - look into it.
We don't encourage real-time trip reports here, so I'm closing this. Feel free to PM me if you've got anything more to add.
