Hi Metrohoud, and welcome! Nice to have you here.
I personally have never taken Lamotrigine, but we have some information about it here:

You can use the Learn section to read about Hyperbolic tapering. Right now, you're doing 12.5% reductions. If your symptoms begin to get worse, it may be a sign that you need to slow things down a bit or reduce by a lesser amount. Sometimes all the reductions can quickly add up and then hit us all at once, so I don't want that happening to you.
Insomnia is a very common symptom while tapering (unfortunately, right?). Here are some links that I hope will help:

Regarding Bipolar, have you heard about using Metabolic Therapy for this? Many people are having complete remission of symptoms by using a ketogenic diet. It might be something to look into.
We look forward to supporting you on your tapering and healing journey!
