I went off Armour (3 grains) six weeks ago after a year of treatment. I started with 100 Synthroid and 1 grain Armour and did fine. Then at 4 weeks I went to 150 Synthroid and no Armour and feel fine. I have noticed I am sleeping better, which was a real problem for me. Also, I'm feeling less fluctuation with fatigue - on Armour if I couldn't take a dose on time I would run down. Granted, this is only six weeks in, but I was really nervous about the switch and have been looking for any downside and there hasn't been any problem yet. I want to see what my labs look like a month from now - if I'm converting well - and will decide then whether to add in T3. Your labs look a lot like mine on Armour. It seemed like I was always flirting with hyper if I took enough Armour to be without symptoms. Good luck whatever you decide. I really believe both drugs are fine, you just need to find out what works best for you.
