Head zaps are only meant to be around for the first 2-6 weeks, if it sticks around longer you should consult your doctor.

That's also about the same time it's supposed to take for you to feel some relief, and through that be able to actually improve your situation and learn resilience and strategies to manage your symptoms.

Make sure you take your dosage as prescribed for the whole period, it takes time to build up the ssri levels in your body, and the sooner they get up to par, the sooner the zaps stop, and you can get started getting better.
