Gym Woes

I really, really want to go to the gym.  No, really.  I'm being totally serious.  It's the major stress reducer for my long, long, long days and weeks at work.  I can't go on Monday's because I'm on-call and it would put me too far away from the clinic.  On Tuesday's I can go but I'm usually too tired from being on call all night (I never sleep well) and working 11 hours.  I get around to going on Wednesday and Thursday.  By most Friday's I'm either on-call or traveling to see my family or Kyle.  Two days a week is not enough. 

What's the answer?  I miss the stair machine.  And the assisted chin up/pull up machine.   Heck, I even miss the curl bars.  What is wrong with this picture??  I'm in a long-distance relationship with my gym.
