I always have a harder time crossing multiple time zones when I am flying east. I expect to face jet lag on the flight over to Ireland.
Symptoms of jet lag include:
- Dehydration and loss of appetite
- Headaches and/or sinus irritation
- Disorientation and/or grogginess
- Nausea and/or upset stomach
- Insomnia and/or highly irregular sleep patterns
- Irritability, Irrationality
Long distance travel can be so much fun.
