Re: How long before T3 kicks in

Question about T3......I've been on 150 mcg Levothyroxine (T4) since my TT. Tomorrow I have to stop the Levo and switch to Cytomel (T3) 25mcg for 2 wks. Then, off all meds for 2wks (which will really suck I'm sure!) to prep for the RAI. Any idea how I'll be feeling over the next 2wks while on only Cytomel? Better or worse? Tired or energentic? I'm just wondering what kind of difference on me the new rx will have. Of course, the next 2wks are busy with school, girlscouts, basketball starts, teacher conferences etc. Am I going to feel up to all that? Or will I be wiped? I really don't know much about the 2. Someone said that T4 is converted to T3 in your body after a couple of weeks. What will I feel like with no T3? Thanks for the heads up and warning!
