I have had this problem where I get sick to my stomach .I'll eat something and anything will set it off.I began to throw up, but it is huge amounts of nothing but clear liquid a little thicker then water.Almost like baby oil. I do this with out any warning it just comes.Its not my gallbladder I do not have one it was removed over 28 years ago.Its not a herna either. I noticed this starting again after I started to reduce my zoloft level (doctor knows im doing this) I also am increasing my effexor (this drug has given me energy). I had this problem last year before I was put on the zoloft and effeyor.But apparently the zoloft controls it to some degree. I was just wanting to know what the liquid is? I also have a problem with my levels of serotonin .When they are low I have server mental problems.I can not remember things and I'm paranoid to the point of being hospitalized. Does anyone know if this liquid could be serotonin because it kinda all happens together.So I wonder what could be happening to my body to cause it to come out like that .If I could figure that out maybe I could figure out why I get sick.What are the reasons and how can we loose serotonin from our bodys?Anyone know?Besides lack of sleep. I realize if I increase the zoloft it will control this but Id like to know whats causeing it, to fix it not just control it.Im not sure its got anything to do with serotonin levels its just my feeling because of everything happening together. Also is this linked to CFS/FM ?
