I'm sure this is ironic...

I have twice now absent-mindedly taken Ritalin instead of another drug. Ritalin is not a good thing to take before bed! I laid awake most of the night last night. I have discovered one thing - I would not make a very good bulemic. I realized about 5 minutes later what I had done and tried to make myself throw up. I can't do it. I guess there are worse problems to have.

This is sort of like the whole chicken and egg question... or maybe it's like the tree falling in the forest question. Either way, it's a good question: If I had taken Ritalin, would I have been focused enough to not take Ritalin?
