Measure
Liothyronine (Cytomel)
Subjects will be divided into 4 groups. The first group will take 25 mcg twice daily for one week. The second group will take 37.5 mcg twice daily for one week. The third group will take 50 mcg twice daily for one week. The firth group will take 75 mcg twice daily for one week Liothyronine sodium: Subjects will be divided into 4 groups of progressively escalating doses. If the study is fully enrolled, each group will have 6 subjects 4 will receive the active treatment and 2 will receive the placebo. The first group will receive 25 mcg twice daily for one week. The second group will receive 37.5 mcg twice daily for one week. The third group will receive 50 mcg twice daily for one week. The forth group will receive 75 mcg twice daily for one week.
Placebo
Subject will take matching placebo twice a day for one week Placebo: Patient will receive a matching placebo to take twice daily for one week.

Determine the Maximum Tolerated Dose (MTD) of Oral L-T3 in Subjects With MS
75 mcg daily with BID dosing

SECONDARY outcome

Timeframe: 1 week

Population: Participants with MS taking L-T3 or placebo

P100 latency will be compared before and after treatment with L-T3 in subjects receiving the active treatment to assess reliability of the test for future assessment of treatment effect.
