I'm not a professional, but I just started my own company and created an S-Corporation which is similar to an LLC in that it limits the liability of you personally. In some of my research I have read that it is not wise to co-mingle your personal finances with the company finances because the courts will be more easily convinced by a plaintiff that you were not operating as a separate entity in the first place and you should therefore be held liable for the full amount sought after.
The Sole Proprietorship you had for the last couple years could legally pay all your personal finances without question. This is the heart of a sole proprietorship, but when you changed it to an LLC that changes the way the finances have to work. If you operate out of your home you can have the company pay for a percentage of your household bills according to the square footage of your house and the footage of the office space used for business.
Check with your accountant. Actually, I think the whole issue can be resolved by finding out from your accountant how you need to separate your personal finances from your business.
