Oh yeah babe, that was the name of the game. Excedrin helped out in that department. More than anything it was the cramps and the shakes. I don't like people raising eyebrows and dropping your sharps bin off and handing it over with shaky hands, well, just doesn't look good you know? I didn't partake in introducing Cytomel namely because I didn't want to mess with another bodily system and what RJ had to say about such a stack. I think you'll be fine with a 2 on and 2 off approach starting low mind you and working up no higher than 80mcg.
The ECA stack is very effective and I probably would start there and work your way to clen if you feel compelled to do so. I had decent results with the ECA but throughout the years I've developed a pretty high tolerance to caffeine and needed something with an extra punch. I'm quite fond of the stuff but I wont run it again for at least a couple of months.
