OH MY! I couldn t decipher the word teetotaller for a minute or so...I finally got it....but I THOUGHT IT SAID, that you had grown two feet taller! and that you had just some how just mistyped something--- what a difference one letter can make! Well, good for you. I m a Teetotaler as well, always have been and though I m not nor have I ever been a professional sportsman I continue to avidly stay in the sport of wrestling entering both collegiate Open and freestyle tournaments. I m 10 years your senior and I coach wrestling as well at John Carroll University. Your symptoms are not uncommon under the scenario of a variety of different situations such as dehydration, hypoglycemia (low blood sugar), intercurrent illness such as either a respiratory infection, viral syndrome, bladder infection, side effects from new medications, or the interaction between a medicine you have always been taking, and something new, an ear infection (viral or otherwise). Your best bet is to keep yourself well hydrated, water is best, take your temperature, get something substantial to eat instead of being a Toast-totaler in the mornings if your habit is to skip or not have much to eat. Are you in acceptable physical shape for where you want to be right now in your life. I don t know which professional sport you are referring but I know they all have their standards of conditioning and fitness while people are actively in the sport Of course, this wanes as we get farther away from the sport and as we age. Notice that I phrased your level of physical conditioning as acceptable FOR WHERE YOU WANT TO BE right now....as opposed to the way you phrased it which was FIT FOR MY AGE. I would expect a former pro athlete to be FIT for their age AND MUCH MORE in all probability at the age of 44. But is that WHERE you want to be. So the coach part of me is telling the COACH part of you that you could probably do better in that department....as can we ALL. I still actively compete in my sport and get head to head with Division I college Bucks....I shouldn t be eating that 1/2 quart of Cookie Butter ice cream I just polished off 10 minutes ago as I began writing this to you....and boy are my kids going to pissed to find it missing from the freezer. Gotta try to get out of the house now too before my wife figures out that I dove into this thing....but hey, I m also being minimally productive answering questions for folks....don t I deserve it? LOL! So, the point is there are a number of things that could contributing to your sense of less than optimal well being. The question is, which is it for you? If you have not had a GOOD SOLID physical with some blood work to include cholesterol, thyroid hormones, perhaps even some other hormone checks such as testosterone, cortisol, and so forth, maybe a good screening EKG to be done, and then, a tight neurological assessment (which is my specialty and BIAS to boot! I put a high premium on brain function---) then, COACH....this is a good chance to take care of business just like you tell your boys or your team. If you would care to address further questions DIRECTLY TO MY ATTENTION for consideration you may find me at: http://doctor.healthcaremagic.com/doctors/dr-dariush-saghafi/68474 Would you be kind enough to leave a little feedback on the response I ve given you as well as a star rating if you feel the information has helped understand your question a bit more? Best of luck to you and your team this season.....as long as you re not the PITTSBURGH STEELERS! LOL! Just teasing you....I ve got a neighbor who used to play for both the Falcons and then, afterward the Steelers...we still talk to each other and he s been allowed to move into the neighborhood...so it s cool! ROFLMAO! Cheers my friend!
