What advice could you share with the groom the night before his wedding?

I am not sure what you mean by this question.  I do not profess to be a counsellor thus not experienced nor certified to give advice.

I believe it's insulting to tell your groom to not over indulge, besides the grooms night is often held the week before and I have yet to meet a groom who has turned up at his wedding under the influence.  I cannot legally marry you or your partner if you are under the influence of substance which could impair your answers required by law.

To arrive at the ceremony venue on scheduled time.

Quite simply put, just enjoy and relax the night before.

Have a relaxing night and stay sober. After all....you are about to enter a new chapter in your life and why would you want anything else but the best for your bride to be.

Don’t overdo it - get a decent night sleep and limit the booze! He should also do a final check to sure everything is ready to go for the big day so he isn’t rushing around on the morning of. The most common things grooms forget are: ties, socks, cuff links and speech notes! 

Ha!   Stay sober

After all the planning and counting down the months and days to the big day - the night before is time to spend with his family and his groomsmen.

Relax, enjoy their company, have a lovely meal, take some photos to remember the night before you marry the partner of your dreams.

Prepare a little surprise for your partner tomorrow, a note or a card saying how awesome they are and how truly special they are to you, and have someone deliver it to them prior to the ceremony, or give it to them when you have a quiet moment during the reception.

Don't take these moments for granted! Give yourself the gift of enjoying everything you have planned together.

Have  good nights' sleep and prepare yourself emotionally and psychologically for one of the most important and precious days of your life

relax and have an early night :) 

The night before the wedding is a special time to reflect on the beautiful times you have shared with your loving partner and to read through your vows, don't try to memorisze them, just relax and feel the love and words you will be saying. 

Its the perfect time to catch up with those special people in your life who will be joining you "tomorrow" for the first step on your path to your future together, but most importantly remember to drink as much water as you can even in winter, eat really well as this will help clear your head , refresh you  and give you the right stuff to help you tackle those nerves tomorrow.

Allow plenty of time to get ready and be at the venue nice and early so you get a chance to relax and talk with your friends, family and guests. Eliminate as much as possible any distractions, hazards or possible delay causing problems at your venue if it has been a while since you have visited (your Celebrant should have discussed this at some stage during your reheasal or after their visit to the venue).

Have a bottle of water handy and a hankerchief in your pocket (someone will need it) just before your partner arrives slip a mint or small piece of chewing gum in your mouth as it will become dry just when you are about to say your vows.

Most importantly relax, take your time and enjoy your day as much as possible, its is your day, everyone is there to see you having the best day of your life and it will go very fast - there are no retakes!!!

My advice to a groom is  to spend time on the night before his wedding with his family and close friends - his last as a single man.  The groom should relax about the wedding - and to remember he will be making a personal vow to the person he loves - he should not worry about 'public speaking'.  It is a promise from one person to another.  It is okay to show his emotions whether he crys or laughs.  Lastly, I would recommend not drinking too much the night before..... he does not want to have a hang over.

Do not be pressured into drinking too much.  Stay calm, have your speech written down, I give my grooms a two page information sheet regarding speeches (and one for the best-man as well)  Try and get plenty of sleep and take the time to read through your vows and know them well regardless of whether you are reading them or repeating after your celebrant. Make sure you have a few tissues in your pocket (for yourself and your bride, just in case). Have a spare shirt handy -  You are likely going to be sweety during ceremony, nerves and such, a spare will allow you to change so you fresh for the reception... after all, it is a long day !  Have a mint before the ceremony so that your kiss is fresh as well as memorable. Thats all for now, though I could go on for paragraphs. Regards,  Ron.
