"i have been on cymbalta for about 6 months. in this time i lost my libido completely, suffered night sweats and couldn&#039;t work out if i was hot or cold during the day. i constantly felt sick both in my head and my stomach and suffered a general loss of energy, probably due to the crazy dreams and loss of sleep. i decided to quit cymbalta cold turkey, and suffered major brain zaps and a general feeling of unwellness. the worst thing was, i didn&#039;t realise this is why i felt so sick and it was impossible to find a doctor who would take my symptoms seriously. none of them knew anything about the drug either. i had to work it out for myself. i&#039;ve lost several months trying to work out why i always feel sick."
