T'Pol woke up sweaty and anxious, as she had done after several sleep cycles recently. Every time, her condition felt worse and she felt less and less invigorated.
"What is the matter with me?" she questioned herself with Vulcan logic, but there was no definite answer for this kind of condition.
"So, the most logical resolution is to see Dr. Phlox and get a full medical examination," she thought, while taking a cold shower to wash her flawless sixty-year-old Vulcan body clean of sweat.
After a while, she dried her shivering body thoroughly using a towel, then wore her grey-and-silver Vulcan subcommander uniform, which contoured every curve of her body, leaving nothing to guess.
A quick sip of tea, a couple of Earth fruits, and she was ready to go.
Fortunately, the Enterprise had been charting the red-gas-giant system for several days, and the estimate was that charting would continue for at least three Earth days, so there was no requirement for her to be in the command center. "I have plenty of time to resolve this," she thought, stepping into the turbolift, where a couple of male crew members, from the lower decks, eyed her nonchalantly.
"Medical bay," T'Pol said, while the turbolift resumed moving, quickly reaching the medical bay deck. "Gentlemen, excuse me," T'Pol said, then headed towards the infirmary.
"Subcommander T'Pol!" Dr. Phlox greeted her, with a smile. "Haven't seen you here in quite a while. You Vulcans rarely get sick, and so on..." he stated, while eyeing her with true interest.
"Indeed, but today, I have to discuss... personal matters," T'Pol answered, matter-of-factly, being logical as only a Vulcan can be.
"But, of course, please take a seat and tell me what is bothering you." Phlox gestured towards the sick-bay bed.
T'Pol quickly sat on the edge of the bed, stretching her long legs. "I have difficulties rejuvenating during my sleep cycles; I see vivid dreams, but I do not remember them after I wake up. Sweating and anxiety also," T'Pol told Dr. Phlox.
