So I was on 30mg for the best part of 2 years. Really considered this as an amazing drug. I felt so well that I decided to drop down to 15mg. Worse mistake ever. I had awful derealization. Felt spaced out and generally weird. So panicked and went back to 30mg after about 3 weeks. Was on the 30mg for about a week or so and saw zero improvement so my psychiatrist put me to 45mg. Iv not had a panic attack for over a year but being put to 45mg has given me the worst type. I'm having like 3 a day. I could be relaxed and boom all of a sudden my heart beats weird and I find I'm not getting enough oxygen like I just can't get that breath. It's terrifying. Iv convinced myself there's something wrong with my heart. Debating as to whether I should go back to 30mg. Any advice would be great please.
