Welcome to HCM. I have gone through the question and understand your concerns.
1. Cresanta is usually taken for a period of 6-24 months. So you can continue it
2. Regarding Metaslim - There are no recommendations for these products for weight reduction.
Hope I have answered your questions. If you have any further queries I will be happy to help you.
