"after reading many reviews i have to say i was very nervous to start viibryd. i started on a day off from work. the first 3 days i had a slight headache and very slight gi issues. after taking tylenol my headache was relieved. definitely recommend taking with food. i just started week 2 at 20 mg. so far so good. no headache or gi upset. no interruption in sleep patterns so far. i feel very calm taking the medication. i will be excited to see what week 3 brings. my kids and husband thanks viibryd already!"
