As a nurse, I say wean yourself off. Don’t play Russian roulette with your brain chemicals. Full dose one day alternated with 1/2 dose next day, for 5-7 days. Then 1/2 dose daily for 5-7 days and so on and so forth.
If the med isn’t working for you, go to the dr, explain, and get something else. He/she will let you know best way of weaning too.
