i had terrible morning sickness at around 6 weeks and to cut a long story short i ended up in hospital for a week due to being so dehydrated from throwing up so much, its a condition called hypremesis and affects 5% of pregnant women in the UK.
when i was admitted they were giving me anti-sickness injections but they made me feel really sleepy so they gave me pills instead, when i was discharged they sent me home with anti-sickness tablets i cant remeber what they were called but when they ran out i went to the GP to get some more and he told me i couldnt and they only way i could get them again is if i was admitted back to hospital, the thing is they really worked and i relied on them, thankfully i didnt get admitted again but i dont think they will give u meds at GP for morning sickness unless ur suffering from hypremesis but i think u should definatly try anyway coz the feeling is terrible and to be honest its put me off being ppregnant again...lol
hope u feel better soon my sickness wore aff about 11 weeks so just try stick it out if u have no luck with doc its all worth it in the end
