Every one wishes to go for herbal medicines but the have been listed that they can also have similar effects as you are experiencing by the medicines prescribed to you. I do not know that, why do you think that these medicines will not work for you and neither do I know that since how long you are taking them. But I would still wish that you must continue taking your medicines for some more time. If the results are not effective then you can try for herbals. Hope so it works.
