I am a 44 year old female who maintains a good weight of 128 - 130 through somewhat regular exercise and moderately healthy eating. I've been taking 75 mcg Levoxyl for over 10 years. In May - June, I frequentely took 150 mcg in an effort to not gain weight while I was NOT exercising and NOT eating well. This may have helped keep off the weight for awhile -- not sure -- but since going back to the correct dose, I have weighed around 138 - 142. In the past, whenever I've gained a few pounds from over-indulging, a few days of watching what I eat and going to the gym have gotten me back down. This isn't working this time.
My question: did I throw my metabolism off by upping my dosage (I know I shouldn't have done that -- just seemed like an easy fix) then taking it back down? Or did that not really affect anything, and I just need to face the fact that at my age, I need to work harder and harder to maintain my weight?
Thank you for your help.
