Hi all just after some reassurance. I’ve been on sertraline for 8 weeks 4 weeks on 50mg and 4 weeks on 100mg. Week 7 I felt great felt like I had turned a corner and was getting back to my old self but the last 6 days I’ve felt like I’ve gone backwards. My sleeping isn’t great again and my anxiety is really bad again. I wake up with the dreaded feeling in my stomach and I constantly feel short of breath ( this is always my most troubling symptom of anxiety) I constantly feel like I need to take a Deep breath in. Prior to sertraine I was on citalopram for 4 years but that stoped working in February this year. Panic attacks came back which then caused me to feel depressed. I cross tapered from citalopram to sertraline and didn’t have to many side affects. So really my question is it normal to stray to feel good on a dose increase then slip back? Is 4 weeks at 100mg long enough to know if it’s right or not or does it take 6-8 weeks to get a more even mod. Sorry for the ramble just wanted to explain the whole story. I really appreciate anyone who takes the time to read my post and reply.
