Deceiving people in business

Q: My aunt gave me a business idea that firstly I should sell food with good fillings like I should sell pizza with some good amount of filling and as soon as people would start buying it more, then at that time I should use less fillings for the pizza. Is this considered fraud, even though I didn't appreciate her or said that her idea is right. So is my aunt doing fraud - sin?

Faskh

Q: My husband (hanafi) was previously married to a shafi girl from a certain town. Things never worked out due to family influence on her side and she went back to her home town. She approached the ulama in her town for help and the ulama sent my husband a letter stating that he has to attend a meeting at a given date and time. My husband never attended the meeting nor answered the calls from her or from the Ulama. Thereafter he received another letter stating that his then wife is requesting for a faskh with a request for another meeting. My husband never attended that meeting as well. He received another letter stating that the faskh went through and that he must go to sign the necessary documents, but never done so.

4 Months after the fasigh went through he proposed to me and we got married 3 months there after, alhamdulillah. Now a few weeks ago, the matter came about, suggesting that he is still married to his first wife.

Regarding the given situation above I need advice on the following:

- Is he still married to her?

- If he is, what steps should he take?

- What are my rights? (At the time of the proposal I never knew he got "divorced" and when he proposed I said that I cannot be a second wife.) 

Taking sleeping tablets

Q: Is it permissible to use or prescribe sleeping pills? After using them, sometimes one is not in his conplete sense and sometimes says what will not usually say in public? Would Namaz be valid in this state? Can it be used if one is unable to sleep? Or can it be used sometimes when one wants to releive himself of worries?
