Cytomel (liothyronine) is active: Leviothroid is T4 which allows your body to covert it to the activated form as it is needed. Cytomel (liothyronine) is already in an activated form, T3. The symptoms you describe are consistent with hyperthyroidism. Cytomel (liothyronine) has the advantage of leaving your body quicker in case you need a thyroid scan. You should discuss your issues with the provider who prescribed it before making any changes.
