Sickness and Exercise

As you may recall, a few weeks ago I started a plan to start running 5 days a week.  Im not in terrible shape, but nobody really wants to see me with my shirt off either, so I decided this was a worthwhile goal for the fitness of it - but really what Im after is the ability to make a plan and stick with it. 
Its been almost a month since i started running, and I've been diligent - I get up every morning early I run, and it makes for a great start to my day:  Im up earlier, I eat a healthy breakfast, and I have more energy for the day. 

A few days ago, I felt myself starting to get sick.  Sore throat, cough, general achyness.  I persevered the first day that I felt poorly and ran anyway, but day 2 I decided to rest.  It wasa  tough call - I knew that even a small break in my routine and the whole thing could fall apart.  3 weeks in is way too soon to have developed a true habit that requires little or no self discipline to maintain (at least for me), so I was pretty concerned about whether or not Id be able to pick it back up once I was better.  I wasnt too concerned about the lost training potential, because as I said, thats really a secondary benefit in this endeavor.  Finally, I decided to rest for a few days - I figured the extra sleep would help, and resting (as opposed to running) had to be the better choice.  After all - the sooner I get better, the sooner I can start up again, right?

That was about a week ago.  Im not back to running.  I cant get up early.  Im sleeping through my alarms.  Im definitely better by now, and theres no reason for me to not be back on the wagon.  Complete, utter, failure. 

At this point its looking like I should have run through the sickness - or at least somehow made an effort to keep the habit - but what?  Get up early and walk?  I dont know.  Regardless, I need to find some motivation to get back to it.
