My Dr. says I have Hypothroid, I have no symptoms such as sluggish, tired, other than normal , for a 69 year old. I have been on levithroxin for over a year and I see no difference than before medication. Should I get a second oppinion? I work in the yard all day and make dinner at night and go to bed around 11 p.m. and still keep going. What are the most common symptoms? I really don t like taking more medication than I need, so please help with answers.Thank you in advance for your assistance.Patricia Bell
