Just a brief update - since completing IR I have started natural porcine thyroid at 1 grain per day;
Step 1 - IR @ 50mg/day for 15 days
Ave morning temp 10 days pre IR : 97.1
Ave morning temp 15 days post IR : 97.0
Ave evening temp 10 days pre IR : 97.8
Ave evening temp 15 days post IR : 98.0
So we appear to have ruled out any Iodine deficiency.
Step 2 - Natural porcine thyroid @ 1 grain / day and reduce IO to 12.5mg/week maint dose
Ave morning temp 7 days into NT : 97.1 (No change)
Ave evening temp 6 days into NT : 98.3 (.3 increase)
Ave daily temp 10 days pre IR : 97.35
Ave daily temp 15 days of IR : 97.5
Ave daily temp 6 days post NT : 97.7
Of note I have noticed a trend downwards in my morning temps since stopping the IR high dose - what was a fairly stable 97.3/4 has dropped down to 97 and then to 96.9 again today. Evening temps have remained fairly stable.
All fairly small numbers, with the only other notable change being a more stable temperature since starting the natural thyroid - much less variability day to day and an overall increase in daily average temp to 97.7
@KSman would love to know if you have any thoughts on this.
