35 yo hysterectomy, w/ ovaries. I have hot flashes, night sweats, can't lose weight, with menopausal systems, FSH level is 1.8 LH level is 1.2, test 37?

Did they check tsh? Appears that your ovaries are functioning. Your thyroid can also cause some of the same symptoms.
listen to your body. The problem is not estrogen deficiency but more likely blood sugar swings. Eating 6 small equal meals with lots of fresh vegetables and slow carb anti-inflammatory grains like quinoa, buckwheat groats, or amaranth, a small amount of high quality protein, and evening primrose oil 3, 000 mg a day with stress reduction and fun exercise through the day is worth a try.
