Thoughts on redosing 2 times?

Hi, It’s been about 2 months since my last roll. Last time I took 150mg and 75mg 90 mins later. Which is my usual that I have been taking for the past year or so (every 2-3 months)

Today I am planning on rolling again, going to a music event and I am taking 150mg and 100mg redose 90 mins later.

Issue is I’m getting there for 8pm, so I want to take my first dose around 8. The event lasts till 4am so would it be okay to redose a second time maybe another 60-90 minutes after my first redose?

I’m just wary of the roll not lasting till the end of the night.

I am also doing 2CB (nasal spray ~4mg per spray)
