Hi, I started on 10mg Citolopram almost 4 weeks ago. The first day was dreadful but after a couple of days I felt great. It's been almost 4 weeks of feeling wonderful and then last night bang all the side effects and increased anxiety were back. I had a very fast heart beat, very dry mouth, hyperventilating, panic attacks, feeling like I couldn't breathe, was struggling to swallow etc. I still felt rubbish today but feel a bit better tonight. I've had my review with my doctor and because I was feeling wonderful he prescribed 2 more months on 10mg. What's going on. I feel like I've jinxed myself for saying I felt so well. Shall I ride it out a bit longer and see if things improve (they have improved about 70 per cent this evening) or do I need to see the doctor about upping the medication? I thought I was doing great and then bam. Is this normal?
