Hi kratz5,

Great question :)! Thank you for asking. Sorry in advance for the botchy English, I'll try to make something coherent 😉

The past six years a lot of things have changed. All these changes made me realize that I'm in a very different place than where I was when I got prescribed the 300 mg at the time. I felt I'd no longer need as high a dosage anymore. Also the side-effects of anti-depressants are no fun.
I wanted to know how I'd feel at a lower dosage. I've consulted this with my doctor and she agreed with me tapering off it.
Below are the first things coming to mind when I think about the changes that helped me come to this decision.

1. Therapy and understanding my mind a lot better:
- I've learned and worked through a lot in therapy (although it took a while before finding the right type of therapy). Especially Schema Therapy and EMDR really helped. I've learned better ways to cope with my depression and anxiety as well as things to be mindful of in order to not exacerbate it.
- Two years ago I was diagnosed with ADHD-i(nattentive type). It explained sooo much and helped me understand myself much better.

2. Self-compassion and daring to be vulnerable:
- Allowing my emotions as well as practicing self-compassion (still a tricky one for me ;)!) have gotten better as well. Trying to be kinder to myself, instead of the usual anxiety driven perfectionism and judgments towards myself, played a major role in getting "better".
- Learning that it's okay to open up or to ask for help - and that you're not a burden for doing so! - made me feel less alone. At times it was like I didn't have to carry all the struggles by myself - like a bit of the weight I felt on my chest all the time was lifted.

3. Change in environment
- Among many things, my study, job, housing, relationships, are different from where I was six years ago. In a good way.

I don't intend to taper off fully right away. It would be nice if possible, but it is not my goal 🙂

Hope this answers your question!

Update in tapering schedule:
After consulting my doctor, right now I'm alternating 225 mg and 187,5 mg a day for two weeks. She told me this way I take an average of 206,25 mg daily.
After this, I'll go to 187,5 mg daily for two weeks. After that, alternating 187,5 mg and 150 mg for two weeks. Then 150 mg daily for two weeks.
This way, in theory, I'd taper 18,75 mg every two weeks because 37,5 mg every two weeks was definitely too fast!

Current side effects are dizziness, fatigue, headaches and major brain fog. Perhaps I'm still tapering too fast.

Thanks for the tip @njoys about the tapering strips! I'll look into them!
