hey there. it is normal, but i think it depends on how long it has been. just talk to the doctor about it if you can. i had to as well. when i stopped, i gained like 10 pounds in a month. my doctor said that was fast, but that he thought it was ok. it just depends. just keep an eye on it. =) i hope you start feeling better. pm if you need anything, i think i know what you are going through. ok.
always, musik
