Dilemma - Synthroid

I have a big dilemma. I had an endocrinologist appointment today. Unfortunately my TSH is still too high, based on blood work from last week and following some from 3 months ago. It's important to keep that level down as a cancer-suppressor. What that means is increasing my synthroid dose. Remember what happened last time? This. I felt awful. Really r.e.a.l.l.y. bad. Right now....this is just bad timing for me to feel terrible again - really bad timing. It might not happen. It's not a huge dose change - I should be fine.

I'm seriously torn. I suppose I have to....but wouldn't this be better in....September????
