have to remember your taking not just one but 2 harsh stims together now so your feeling is quite normal.
lower the dose of everything in half, take caffine at around 200mg see what happens after 2 days,raise the dose slowly at normal intervals until you start getting these anxious feelings again and then go with the last whole dose.
me personally,with 800mgs caffeine I get jumpy and I am resistant to stims.
so try 60mcg clen,50 ephd,200caffine and go up from there.
you have not taken these together so you need to figure your threshold is all.
