"i&#039;ve only been on brintellix for 3 weeks and i am about to reach my &quot;therapeutic dose&quot; of 20mg as prescribed by my psychiatrist (started at 5mg and have been going up 5mg each week). i&#039;ve experienced zero nausea which seems to be the biggest complaint people have. i was warned to take the pill with a full breakfast though so maybe that has helped? i&#039;ve also not had a decrease in sexual desire nor ability to perform which is awesome. by the second day i felt almost intensely cheery and had great urges to do artistic activities. the only side effect i seem to have had is very vivid dreams. no nightmares though. just high-def dreams about walking my dog or shopping."
