Muscles sore and ridicously stiff after riding
Have think about your bike fit, I once had horrendous ITB pain from setting my seatpost just a few mm too high. There's plenty of conflicting advice and opinions you can research.

As well, are you doing any pre/post ride stretching or body care? I use a foam roller on my legs, just a few minutes in the morning and evening (I commute to work &amp; back) does wonders.

Finally, rest days are important! If you're going every day from a history of not riding, kick back and let your body repair itself.
