First scenario is when I want to go off medication. If I am taking 5mg should I take the next lower amount i.e. 2.5mg consistently for 2 weeks or alternate between 5mg and 2.5mg. Day 5mg and day 2.5mg or 4 days 5mg and 1 days 2.5mg, then decrease i.e. 3 days 5mg and 2 days 2.5mg, 2 days 5mg and 3 days 2.5mg and until I slowly replace 5mg entirely with 2.5mg?

Second scenario is when I want to transition to another medication. I do this like what I described above, except alternating with new medication and starting with small doses and increasing until I get to the dosage prescribed by psychiatrist? Like if I was prescribed 5mg, do I start with 2.5mg and gradually go up?

Thanks!
