You're always tired.
Is coffee the only way you're making it through the day? Are you restless and not sleeping at night? Do you wake up cravings more sleep?
Do you find yourself constantly retracing your steps or forgetting why you came into a room?
You can't concentrate.
Are you always scrambling for your words or finding it difficult to complete a thought? Is your "to-do" list never done?
Your mood is all over the place.
Are you a ticking time bomb? Does the smallest event set you off?
You're finding it hard to engage.
Do you feel like a bore to be around? Are you having a hard time holding conversations?
