Finding things hard

I've got a 6 month old son and have recently found out I'm pregnant again.

Both mine and my husbands family said to us to NOT get pregnant again until we've enjoyed our son for a couple of years. We got pregnant by ACCIDENT. I was on the pill since I gave birth to my son and my doctor is currently investigating how I got pregnant on the pill.

I've just turned 6 weeks pregnant and am on holiday with my husband, son, parents and sister. I can't drink any alcohol and some foods your not allowed to eat when your pregnant. I'm finding it SO hard not to eat the things I'm not allowed and keep having to make up an excuse to not have any alcohol which is extremely hard as I used to drink a lot of alcohol whilst on holiday. I'm just beginning to get some slight nausea as well so having to hide that is super hard too!!

Has anyone got any tips on how to not give anything away?
