Consuming alcohol

Q: I have been reading a few things regarding alcohol and the Islamic views on it for a lesson I care for. I have some questions about it.

1. If someone consumes alcohol and then leaves it and repents will Allah forgive him.

2. Is there any rule that is someone consumes alcohol he cannot perform namaaz and touch or recite quran for 40 days as alcohol stays in the body for 40 days.

3. What are some of the ways one can repent about the sin of consuming alcohol?

Yellow discharge

1. Is yellow discharge at the ending of haidh regarded haidh or istihadha?

2. What if the is slight sign of blood but most is yellow?
