If your boyfriend is overweight and drinks a lot then you've no hope other than a diet and abstinence (from the drink that is!). If neither of these things then really there are only a few effective tratments. The most effective is surgery to tighten the flap of skin/membrane at the back of the mouth that causes snoring. There are also chemicals which are said to be partly effective (ask a pharmacist/doctor). Other than that snoring is often lessened when sleeping on the side - an old fashioned cure is to sew something into the back of a pyjama top to make it uncomfortable to lie on your back. Sleeping slightly propped up will also help. Snooring is horrible to live with and it needs to be taken seriously. At the very least your boyfriend's sleep (and your's) is being ruined. More serious is a condition called sleep apnoea, a condition where snooring is so bad that oxygen levels are seriously reduced. This can lead to a heart attack and death. If when snooring your boyfriend seems to stop breathing for more than a couple of seconds at a time, get him to consult a doctor
