I am an emotional person and cry very easily. I went to a wedding this weekend and cried -- and these were not even close friends! I'm getting married in less than a year and I know that I will cry profusely. Are there any products such as eyedrops or something that will keep me from crying, or from crying so much?
Instead of trying to prevent your tears (no drug or eyedrops will stop you from having overwhelming feelings), you should revel in your emotions -- crying because you're happy is an amazing feeling! If you're worried about your wedding pictures, consider taking formal shots before the ceremony, when you may be nervous but not yet overwhelmed. Just make sure to arm yourself with a good waterproof mascara and tissues, and then sob away. People love when brides cry, and it will probably be touching for your groom too.
