I've been on a very low dose - 200 mg at night - of gabapentin for a couple of months. First couple of weeks I experienced a headache and mild nausea, which of course were unwanted effects, and sleepiness, which I did want since I am taking it for the drowsiness factor.
Next 2 -4 weeks, all side effects subsided, including unfortunately the sleepiness. In the past 1-2 weeks, side effects of nausea and headache are back, it's as though I have a moderate hangover every day. Any ideas why side effects came back on same low dose, and what I might do to address it? Thank you
