"i have been on cymbalta for about 7 months so far right and will continue to be on as instructed by my doctor. i am one of the luckiest who had no insomnia nor stomach problems because of it. i had bipolar and cymbalta started to make me get better in its second week. the first week was slightly difficult, i had some cold hands and swinging mood struggles but they were pretty tolerable and went away fast. it&#039;s easy to focus on sports activities with it and it doesn&#039;t affect your nerve /muscle system badly. the withdrawal should be very carefully handled though because even when i forgot to take my pill one day, the next day i started having stomach and attention problems, low blood pressure and fatigue."
