You should never cold turkey anything. Your supposed to go down a little (25mg maybe) at a time with a week or two inbetween to be safe. You might try taking 75 or 50 again with a doctors consent and wean yourself off slowly or get hospitalized so they can keep a closer eye out if you think the symptoms of withdrawal are not getting better. Try to think of thos as a struggle with the end goal of stability again. We will always have hiccups its part of life. I wish you luck!!
