Could My B Complex Supplements Be Causing My Urine To Smell Sweet, And Should I See My Doctor?

I have asthma, but I have recently noticed last week I started taking B Complex for my tremors per my neurologist. My urine has started to smell like pancake syrup. I am overweight and I go to the gym three days a week to work out. I don't think I have a UTI for I do not have any other symptoms. Do I need to see my primary care physician? I also crave chocolate and caramel. I am trying to stay away from it because I am allergic to corn/wheat/soy/egg products, but it is very hard for me.
