Ooh. details!
I realise I just contradicted myself. I started another thread re. the effects of MX134 - I was being given a lot of complicated tasks way over the top of my head (not just monkey janitor work that they usually give junior staff) and people erm… overestimated my capacity sometimes which made it a bit funny. OD perhaps. 
Speaking of which, I tried p94 again. Same thing - felt organised and mentally sharp. Am still wide awake after a 12 hour shift and feel like I could go on working for another 6 hours with the same capacity. Stable version of speed in a bottle?
I suppose I could just use the pheros for myself as opposed to checking people’s reactions…
