Finally Feel Good, Dr. Says Overmedicated

Because my TSH is suppressed (.19) while on 10mcg lio, 75mcg levo. My energy and concentration levels are sooo much better since 75mcg - but my new Dr wants to take me down to 50mcg, citing risk of osteoporosis for a low TSH. But I don’t want to go back to feeling so lethargic and brain foggy which is how I felt on 50mcg. Has anyone gone through similar? I don’t think I have a choice in the matter but just looking for any similar situations. Not sure what to do honestly
