DelMarVa Chapter > > Hello Marty and Will. Will: I find your experience difficult to explain based on the report which I quoted in my previous post. This says that if you allow up to 1 hour after taking a tablet before you start exercise, your blood levodopa levels will be unaffected by the exercise. The other point which you raise about jobs which require fine motor skills using your dopamine very quickly, is equally hard to understand. As I understand it, dopamine can be imagined as a small lever, which switches powerful devices (our muscles). The dopamine merely instructs the muscles to expand or contract, and is not used at a greater rate when we are thinking hard, nor when we are exercising violently. I would suggest that what your experience shows, Will, is that you can do the jobs such as sweeping the yard in a condition where you are at a relatively low level of medication - that is, more Off than On. - a state in which you could not possibly cope with delicate jobs. In fact, delicate jobs demand a greater degree of control from our medication than coarse physical work, and it is much more difficult to achieve the correct tablet dose to allow you to do the fine work for a prolonged period of time. What I am trying to do here is find explanations for your experience which are consistent with the findings in Paper A, which strikes me as a well-thought-out piece of work which should be respected. As far as the original question about the duration of a tablet goes, i suggest that if you check, you may find that you were getting a part of the penalty due to starting your exercise too soon after taking the tablet. On a purely practical note, I strongly suggest that the most effective way of coping with shorter duration of tablets while exercising ( i.e. the experts got it wrong, and it wouln't be the first time) is to bring forward the time for the next tablet, and not to take an increased dose, as that would probably exacerbate (good word, that) any tremor which you may have. I would be interested in your views P.S In response to Joe Bruman's delightful description of the sky at night having holes where the light shines in, I quote a verse by that renowned expert and eccentric Spike Milligan on the subject: There are holes in the sky where the rain gets in but they're ever so small - that's why rain is thin.
