Not really. I only had the lethargy that one day. I cramp up here and there, but it goes away after a few seconds. For example, when i have my arm curled and i extend it real fast, my forearm by my elbow has a cramping feeling like some one just punched me. But that's it. I might get a cramp here and there every so often though, but like i said it goes away within a few seconds.

I believe i also said it before, but it really helps with DOMS. The only thing thats sore on me right now are my traps. But look at all that i did for them, plus I've never shrugged that much weight before.

I'm also getting bigger, especially my traps and arms...according to my wife. I've always asked her if i was getting bigger. She'd barely ever tell me yes. Now she definately notices it.
