Maybe for some people ssri wasn’t a option
A lot people don’t feel any positive effects through ssri for long periods of time but negative side effects, especially for people who’s actually having cfs but was diagnosed with depression, I’m thinking drugs like 5ht3 antagonists might be an answer for these people.
Check out if you feel sweaty, blurred vision, anxious or have a temperature after taking ssri, if you don’t feel comfortable but don’t have any of these, try to add up bit more doses and find out. Feeling heart pressure, diagnosed with IBS or low quality of sleep might be a sign too.
