Do you find routines to be near impossible to establish / follow (eating breakfast, waking up within the same two hour period, taking a shower, etc.)? Are you unable to remember anything without a constantly visible list / alerting system? Do certain irrelavant noises cause you to instantly lose all concentration? Do you have a tendency to forget to pay bills for months while racking up several hundred or thousand dollars in fees? Do your relationships suffer as you often go months without remembering to talk to close friends? Are you usually 5 - 10 minutes late for all meetings and social functions due to an inability to accurately predict durations and intervals of time?
Maybe then!
