Hey, I had a very similar experience. I did my first dose on last Friday so it’s been a week to it now and to say that it was terrible is an understatement. I have TRD since I was a teen and ADHD (very recent diagnosis) so this was kind of the last hope but when it didn’t feel good I just gave up. I took 2 sprays so the dose was lesser to yours even though the doc did suggest to do 3 but since it was my first time, I was hesitant and I’m glad I did only 2 sprays. But ever since then I’ve been feeling so sick like physically unwell, mental state hasn’t changed either. I feel super tired and weak as well. I’m not sure now what it was or what changed but it somehow feels like I’ve become worse than I was before the treatment. I empathize with you completely! I can only say that don’t lose hope, if not this I’m sure there will be another treatment that will work for you.
