I have a similar experience with counting. I've always harbored a fear of choking on Advil, Tylenol, etc. and music theory plays an integral part in pill consumption. For me, there's four notes in every measure and the Tylenol must be swallowed exactly as the 32nd beat occurs (at the conclusion of the 8th measure). That's per pill. If I screw up the count, I'll start all over again. Therefore, if I'm taking 4 Advil, I'm lucky if I can get them all down in 10 or 15 minutes.

BTW, your OCD is far from uncommon. And, in addition, I'm sure you're brighter than 95% of the population.

I know about this.

My father in law has undiagnosed OCD, and most likely, he also has Tourettes (no spontaneous cursing, he just has a tic where his shoulder twitches when he gets nervous). He frequently takes his wallet out and counts his money, and one of his more prominent obsessions is that he dates EVERYTHING. He will even write the date of purchase on the inside band of his underwear! And it's guaranteed that somewhere on his shoes, he'll have a date on them. I've actually adopted some of this, in that I will place the date of purchase on major appliances, but don't date any of my clothes or other inconsequential items.
