"This medication has had the adverse affect for me. After being diagnosed with Hashimoto's, my doctor expected that this medication would help me with brain fog, energy and tiredness. I experienced the opposite. Within a few days of taking the 60 mg dosage I felt worse. I began sleeping extremely heavy, had a huge amount of trouble waking in the morning, and could barely keep my eyes open past 8:30pm each night. I gained five pounds in two months even though I had improved my eating habits and exercise. I began getting these dull headaches on the top of my head. I became extremely irritable with everything which is not my normal disposition. Dr told me to stop taking immediately and is prescribing Nature-throid. Will see how that goes."
