Dark Therapy helped me quite a bit, so did making my room as dark as possible at night. I still have issues staying asleep, but I am able to go back to sleep fairly easy. I honestly believe most of my current sleep issues are caused by the lamotrigine I'm tapering off of. When I have trouble going to sleep and staying asleep I use 5mg instant Melatonin with 300-600mcg time release melatonin. Sometimes that isn't enough or just is not therapeutic and I'll eventually try l-theanine if I believe I can keep myself from thinking too much. I have found l-theanine calming and it can promote undisturbed sleep with very strong REM sleep (almost as sharp an experience as vivid dreaming), however, it can also make it harder to go to sleep as it makes it easier to clearly focus my thoughts and if those thoughts are worrisome it becomes difficult to sleep.

I think it would have been prudent to use a taper plan that reduced the dosage by 25mg per week. Small gradual reductions make the process far easier in my opinion. In fact, I have found that by avoiding huge drops in the taper process I can withdraw at a higher rate than otherwise as my CNS is placed under less acute stress. It's kind of like the difference between jogging 3k every day or 12k once a week. Moreover, the large drops in dosage are more likely to disturb sleep and sleep is integral to speeding recovery.

Just as important is to make sure you're getting all the nutrients necessary, not simply 100% dv. Under times of stress certain nutrients like magnesium are rapidly depleted. When I first started my taper of lamotrigine I spent the first week and a half with body aches, lethargy, and a headache. My understanding of what goes on during withdrawal led me to believe I wasn't getting enough magnesium, so I tripled my supplementary intake and in two days I was back to daily exercise and decent sleep with normal amounts of after exercise inflammation. It really was as simple as matching a nutrient to a symptom, which really highlights the importance of good diet, especially while withdrawing from certain medications. To provide some context I was already getting ~140% the daily value of magnesium with over 100% coming from diet alone.
