"i am in my late 40&#039;s and struggled with insomnia for years.  got by with zopiclone for a long time but it started to become ineffective.  finally, after many fears about side effects, i tried quetiapine.  i have gradually increased to 50 mg at night which seems to be the optimal dosage and i have been  sleeping very well and feeling much better.  main side effect is dry mouth so i have to be mindful of dental care.  no increase in appetite or sweet cravings which i feared.  it is worth trying if you are really struggling.  very happy with this medication."
