Hello Welcome to Thyroid Board
Yes with proper treatment you should return to normal, or at least almost normal. If your symptoms persist it is likely your medication is off (most likely too low) or the med doesn't suit you in some way. It does take time for your meds to work so you need to be patient but don't settle for anything - you need to have your labs checked every 6-8 weeks after each dose adjustment to see how your labs have changed and symptoms (hopefully) improved. Getting your labs "within range" isn't sufficient treatment - full symptom relief should be the goal. Make sure your doc checks your FreeTs along with TSH, treating based on TSH alone just doesn't cut it. Usually people need to have their TSH around 1 or lower and freeTs somewhere in the upper half of the range in order to be symptom free.
