Q. Iam a bipolar and presently on tegretol medication.I found this to be the best way to get my doubt clarified. I am a bipolar and presently on tegretol medication. My doctor frequently changes the meds and he has tried variety of medicines before prescribing tegretol. He changes the meds every time when I visit him for routine check-up. I am bit confused and obviously cannot question my doctor as I repose faith and confidence in him. I found this to be the best way to get my doubt clarified.

A. Are you being treated by your GP? I would suggest if you are having trouble finding the right combinations it might be a good time to ask to be referred to a Psychaitrist. GP's will do their best but like anything specialized they only have a certain amount of knowledge and a specialist in the field could be more help. I also think that other treatments along with The medications like theropy and group theropy, excercise, good diet, plenty of sleep etc helps a lot too... Try to be patient it is a process to get everything in place that will work the best for you... everyone is different and the .mmedications and treatments that work for one may not work for another...
