Hi Gail. I can understand your situation, I think we all struggle with dosing our meds. Even though I was diagnosed with PD 17 years ago, at age 46, I label my situation as "moderate" PD. For better (I think) or worse, my movement disorder specialist encourages me to experiment (within reason) with my meds. I've tried Sinemet, Sinemet CR, Stalevo and Rytary. I've also been on a couple of agonists (Requip, Mirapex) with disastrous results (impulse control disorder) and a long and difficult withdrawal. So, I might be able to offer some perspective, with the usual disclaimer that I am not a medical professional, my comments should not be misconstrued as recommendations and any changes you might consider should be approved by your doctor. Having said that, I offer the following from my personal experience: - Know thyself: PD, as you know, is not one-size-fits-all. Each of us reacts differently to the disease and to the meds. I have tried (somewhat successfully) to identify objective circumstances (eg. tremor in my left arm, stiffness in my back) which signal that I am getting low on carbidopa/levodopa (C/L) or have more than I need in my system. I've gotten to know my dystonias (spasms, etc.) and dyskinesias (head rocking) and, importantly, what it feels like to be "on". I have found this knowledge indispensable for trying alternate dosings. (BTW, my back stiffness and pain are the result of excess C/L, not a lack thereof.) - Symptoms have many causes: I find that, day to day and even hour to hour, my symptoms change - they get worse when I'm stressed or anxious, or when I'm tired, or hungry. Some times the meds have no effect after a meal and I have to double up. Some days it seems like I just can't get the dose right There are numerous causes. I've found it useful to identify my triggers so as to distinguish when my arm is trembling due to stress vs lack of meds - Meds are not constant: If you look at a chart of the amount of C/L in your blood in relation to the time elapsed since you took the meds, you'll see that, in the case of standard C/L 25/100 mg, that the blood concentration climbs to a peak in a half hour or so, then declines, with a "half life" of an hour to hour and a half. So, if we use your example, the chart of C/L concentration would look like saw teeth. I have found that, using a dosing level of two pills and an interval of two hours, I can avoid the depths of the decline and maximize my "on" time, my time in the "therapeutic window". (More of this technical stuff can be found by searching for pharmacodynamics and pharmacokinetics of the med in question). - Meds can "confuse" symptoms: Many mornings, I am almost asymptomatic for 1 to 3 hours after get up (which I attribute to the release of dopamine during the sleep cycle and just being, overall, relaxed). Within minutes of taking my first C/L pills, I get noticeably worse and it takes 10 to 20 minutes, sometimes more, for things to stabilize. My theory (unconfirmed) on this is that the dopamine flooding the brain is absorbed nonuniformly, causing an imbalance. So, say the area controlling movement on the right side of the body absorbs dopamine faster (or has more neurons to absorb it) than the part that controls the left side, the symptoms may change more and faster on the right side. For example, sometimes after taking a round of pills, my left leg will spasm while my right leg is just fine. This kind of imbalance often forces a compromise between symptoms. - Beware the placebo effect: There seems to be a recognition in the literature that the placebo effect is quite significant with PD. I've had some experience with my expectations clouding the interpretations of my meds experiments. - Consider keeping a log: I'm really terrible at keeping logs, but have no doubt as to their usefulness. Start simple, maybe tracking "on" and "off" periods along with med timing. See if there's a correlation or pattern. Maybe add a symptom or two to the tracking log. You might observe, for example, that a tremor gets worse long before the next scheduled dose, suggesting a shortened interval between doses. - Remember, you're shooting at a moving target: PD symptoms change with time, and a med regimen that works well today may not be optimal three months from now. OK, I've rambled on quite enough. Please forgive my verbosity. Again, from my perspective, these are things that I've had to consider when contemplating adjustments to my meds. I'm still learning. In the meantime, I feel that I've gained some more insight as to managing my days. Cheers.
