That is pretty funny, and maybe true, it could be boredom while running sometimes.  I don't get that high until I am done, maybe I need headphones.  Thank-you for the reply, and I will pursue the test further if it happens again.  In the meantime, I will watch my intake of carbs carefully.
I appreciate your response, learned alot from some of the info I looked up.

Thank you for your reply.  I actually did have a thyroid test last year due to eye lash loss and poor ability to sleep, and weight gain.  
I do exercise regularly, and have a healthy diet, so my Dr. was puzzled also.
The thing that really scares me a bit is the sweet smelling breath that preludes my reaction each time it has happene.  It has not happened often because I usually don't have sugar, and alcohol.  The other thing that was making me think that perhaps you have a point with the ketoacidosis, is that when I begin to do a speed walk or run, halfway through I get this feeling like I want to close my eyes and go to sleep, like my steam runs out fast.  Could this also be due to a drop in glucose in the blood?
What kind of test do you recommmend  I go for to find out about this.
thank you so much

If this only happens when consuming sweets and alcohol and you don't consume these very often I don't think you have a problem.
Wanting to fall asleep during running or speed walking sounds like boredom to me.  I usually get a natural high.
If your steam runs out fast sounds like you might be over doing it a bit.
However if you want to take the time and money then I suggest the following:

ketoacidosis is severe ketosis causing the pH of the blood to drop below 7.2, this can be checked by a doctor through urinalysis test. Or Ketosis can be checked by using special urine test strips which measure the level of ketones in the urine which you can obtained at local drug store.
Blood Glucose test for diabetes by doctor will get you started.  It can tell if you are hyper or hypo-glycemic which hypo is diabetes and doctor will probably want further test done to verify and confirm.  Or you can buy a Blood Glucose machine and strips at the drug store and test yourself by a ***** to draw blood.
If positive then you will need to go to doctor, if not, then back to the drawing board!

Good Luck

Does this still happen when you don't drink?

With thyroid disorders many of us have problems with sleep.  We get to sleep alright but wake up after an hour or two and stay awake.  I've had  heart racing and tingling in my hands and arms.  But I never have passed out, came close a few time due to sock from a few injuries.

Diabetes has fruity or sweet chemical smell with ketoacidosis, however my husband had an acuity ammonia smell.  
A fruity odor to the breath occurs as the body attempts to get rid of excess acetone through the breathing. This is a characteristic sign of ketoacidosis, which may occur in diabetes, and is a potentially life-threatening condition. Diabetic ketoacidosis is a complication of diabetes caused by the buildup of by-products of fat metabolism (ketones), which occurs when glucose is not available as a fuel source for the body.  Symptoms of type 2/adult diabetes are: Increased thirst, Increased urination, Increased appetite, Fatigue, Blurred vision and  Slow-healing infections.  
Maintaining an ideal body weight and an active lifestyle may prevent the onset of type 2 diabetes

Go to the emergency room or call the local emergency number (such as 911) if symptoms of ketoacidosis occur:
Increased thirst and urination, Nausea, Deep and rapid breathing,  Abdominal pain, Sweet-smelling breath  or
loss of consciousness.

You should have your doctor check this out if it persists before any of the above occurs.It doesn't sound like a casual alcohol problem, but I could be wrong.  Perhaps others have more of an insight for you.

Good Luck.
