Thank you so much for your very helpful information.
First of all, I would be sorry for the mistakes I made, currently I take 150mg (three pills) rather than 300mg. I started 150mg three weeks ago, because I felt my emotion got more often unstable than I used to be, I took two pills for a long time with satisfactory effect untill around three weeks ago. Even when I was good, I felt unreasonably down occasionally, and I got sweat on my up back right since I took zolof more than one year ago. Af first, I thought it might be the side effect of zoloft, but after I increase the dosage to three pills, the sweating got better, so I guess it might not be the side effect of the drug. I found it is more difficult for me to cope with the stress than the time before I got ill, may I ask whether I can redjust my dosage from time to time according to the change of my emotional condition? say sometimes from three pills to two, or from two to three, if so how long is the minimum duration? you said having two episode of depression, I should consider to take drug long term, what do you mean long term? all my life or several years, since the relapse rate is 90%, scaringly high.
