Mirtazapine for anxiety

So it’s now been a full 42 days since I started taking mirtazapine. I was on 15mg until 6 days ago when I was told to increase it to 30mg because I was starting to feel a little unwell again. Now I am feeling even worse. When I first started taking mirtazapine it quickly gave me my appetite back, made me interested in things again and I was on the way back to normal again. What happened around day 27 I don’t understand. The medication says it can take 4 to 6 weeks so I should be feeling much better by now yet I can’t even sleep due to anxiety and the negative thoughts that antidepressants should help with.

Has anybody had any similar experience or know what is going on? Thanks

You increased 6 days ago, maybe give it another good week to judge?

hi did things improve on 30mg
