Oh no tutu, stay strong for your little one now. Heard that if mum is sad then bb is sad too. So stay positive and happy. It's not easy, i also went thru some unhappiness, but my hubby kept on reminding me to stay cheerful.
Talk to your hubby.
As to what to drink, so long moderate, then should be ok. Don't drink a lot. Guess u are badly affected by MS. Try to figure out and find a way to cope with it. Go for a walk or movies or shopping to relax yourself.
