Hi Callista,
If your doctor is willing to fill 6 months of prescriptions, you should be fine as long as you bring the prescriptions with you, depending on what they are. With a prescription and your passport, you should be able to bring most medicines into most countries. With that evidence, you will not be accused of trafficking.
If you are worried about your medicine getting stolen, then you will need to make arrangements to have your prescriptions filled while you travel. However, they may not be available. Check with the US State dept. http://travel.state.gov/ to find out if your medicines are legal. If they aren’t then you won’t be able to get them filled. And you might want to reconsider bringing them in.
