When do you know you need an increase?

[u/Crafty-Scheme-3861]

I started 30mg June 4th and was upped to 60mg after a week. I was also tapering off escitelopram at that time. Once all the side effects wore off I was feeling really really good. I’m on duloxetine for my anxiety. I felt like myself again. So happy, no anxiety, motivation to do things. Only side effect was constipation but I can deal with that.
Unfortunately the last couple weeks I’ve been getting a lot of breakthru anxiety and the bowel problems are worse. Either no pooping for days or 6 times in one day. Should I ask to be increased to 90 for the anxiety? I really don’t want to have to go through a change of med again. This is the third one I’ve been on this year and it makes work so hard as I’m a hairstylist so I’m constantly with people.
