i remember posting something very similar after my first couple of sessions on the starting strength routine and as predicted by everyone that kinda just goes once you get used to squatting regular. I have now been doing the program for 5 weeks squatting 3 times a week and bar the after training soreness by the morning i feel fine still little weak (in a good way that feeling that lets you know you worked hard in your workout last night) but by my next session im ready to go again, in fact you actually start to like the feeling you get :-) stick it out as i did its well worth it
