Ok guys I'm new to blue light although have been reading through the forums for about 3 years now. In short I want to take some diphenhydramine, and have taken it once before about 2 years ago. I'm aware of the trip and would be interested in trying it again although I have been drinking lean (promethazyne and codein mixed with sprite) all day. I have taken about 40mL of the syrup in the past 10 hours. Will I be ok to mix them? I want to take the diphenhydramine tonight.
