shan70,
I agree with dee, as this has been my experience. But, I also think it depends on what mg the increase is. Some Doc's (and patients) feel you shouldn't feel a difference, so therefore the dosage is raised so slowly, the patient doesn't notice. By the time the desired dose is reached, the patient's feel the benefit without the transition. This is helpful for Panic patients.
Hope this answers your question,
