I have to say that going to a higher dosage has some down sides, after the workout and your home having a meal, everything is good. But in my case last night I went to get up and go get some more food and.. nothing.. my legs gave out and then the pain.. oh the lovely pain, haven't had that feeling since the days of being very young and over training.. today I'm still having issues moving around and feeling every bit my 40+, I'm starting to look forward to my S4 hits during the day as they allow me to actually move around somewhat normally. On the upside the upped dose has me lifting and doing way more weight & reps.
