Planning to roll for the 2nd time ever tonight. Dosage advice?

My first time (over 3 months ago) I took 50mg and had severe comeup anxiety, but once that passed in 20 minutes, I felt fantastic. I see a lot here about doses below ~70mg causing anxiety, but I am quite light (43.5kg). I'm thinking of taking the same dose, maybe a little more around 60-70mg but wanted to see if that's a good idea. I know that comeup anxiety is pretty common and I'm thinking the fact that I had a good time after the comeup means the dose was fine for me the first time. Thoughts?
