The way I see it, you haven't got much to lose.... You might actually have a whole lot to gain. Keeping a positive attitude is key. If it doesn't work then you try something else. Don't give up. Eventually you will find something that works for you.
Like you said, give the med time to work. Take the dosage as prescribed and unless you are having severe side effects stick to it.
Please don't think this is the end of the line. You deserve to be healthy and believe that one day you will be. This med could be it.
Good luck! You will be in my thoughts. Let us know how it works out.
