My GCS with McGinn is 11 days from now.  I have been off Estrodiol for 3 days.  I am still on Spiro, though.  I started getting a headache this morning, which has continued all day.  A dull all over headache  Similar to last year when I went off HRT for FFS.  I expect I'll have a headache for most of the next 11 days.
I will be off work for 13 weeks.  I am incredibly lucky that my employer is paying my full salary while I am on "short term medical disability".  
I won't start taking E again until the second week in June.  Along with the use of a prescription testosterone cream.  McGinn want's her patients to maintain a T level that is in the normal range of a cis female.
