For context I’ve been on celexa/citalopram for a little over a year now, 40mg for the last 5/6 months. I started noticing extreme GI upset such as vomiting pretty much everyday, consistently nauseous, etc along with gaining a substantial amount of weight since the time I started on this medication which is highly unusual for me, considering my diet/activity hasn’t really ever changed. Given how I’ve been feeling my psychiatrist thought it would be a good idea to switch to Prozac/fluoxetine 20mg I was curious if anyone has had any experience with similar experiences, I get really nervous starting medications and any advice or input would be appreciated! I suffer from GAD, depression and PTSD, If that helps at all! Thank you in advance!
