I was recently on fluoxetine and it worked for years and had a bad panic attack which lead to months of GAD. I then switched to Lexapro and had to get off of it due to side effects not subsiding. I am on I believe day 5 of Buspar and I'm feeling a good bit of brain fog, nausea, dizziness, drowsy. Etc. Is this common with the first week? Should I continue to take in hopes of getting rid of the side effects ?
