Shaking after workout - OK? Normal? Anyone?

I've been really pushing myself lately.  I've taken up jogging, which I totally love and totally can't believe that I love. :)  This week, I've been pushing myself to go further, faster (although my jogs are still only 40 minutes long - I just go even faster now.)  

I've had times where I feel like I might throw-up by the end.  But... it passes, and I think that's OK.  But the last few days I've been really shaking after my workout.  Like even for 30 minutes or more afterwards, my fingers are still shaking.  

Is this a low blood sugar thing?  Or an "I'm pushing too hard" thing?  Or does it just come with the territory for those that really push hard in their workouts.  I do try to stay hydrated, but I sweat a TON so I suppose it might be dehydration.

Any ideas or experiences to share?  Thanks!!

I have had that happen.  Make sure you are hydrated before exercising and if you sweat a lot get some electrolytes in as well.  Also fuel up - I usually have 1/2 banana and peanut butter, sometimes on ww bread.  If I workout intensely for 45 minutes or more I have a snack after or something during if I am going further.   I don't know anything about sleeves as far as sugar sensitivity, but my post-workout snack is generally a Tbs of peanut butter with 1/2 Tbs of local honey or 8oz of low fat chocolate milk.

Could be blood sugar.  I always have a snack about 30 mins before I work out...usually a few crackers and hard cheese, or banana.  If I don't, I get the shakes during the workout.

Congrats on the running!  I kind of fell into it too, and love it!
