On 11/16/20 I had gastric bypass. I had my thyroid removed, half 25 years ago, half 10 years ago. I also had a full hysterectomy 12 yrs ago. No hormone replacement. I feel like the world's slowest loser. Tomorrow starts month 3 and I'm only down 19 lbs. However, in May '17 I weighed 343, lots of up and down in between (back up to 291 May of 20) but was down to 261 on surgery day, only 19 lbs so far since surgery, keeping calories at 800ish. I'm either freezing or sweating. 2 weeks ago after calling the endocrinologist cause I felt awful, my tsh was .09 so I was hyper, now he has me skipping one day a week of my .125 Synthroid. I am not losing like the reports I see, I'm exercising a little, treadmill & bike 10 min 2-3 times a day most days. I'm feeling frustrated because my results don't feel commensurate with my effort. I'm mortified at the thought of increasing calories. I am getting my protein. There are so many opinions and schools of thought regarding calories. I'm just never comfortable, ice cold or sweating when I shouldn't be. Seems weird. Thoughts?
