extreme nausea

does anyone have any remedies that have worked for them with morning sickness? I am currently 11 weeks 2 days but i have been only able to eat cereal and lately i can't even eat the cereal either. water makes me feel more nauseous so i usually just take a sip and feel done with it. Been to the drs and they've given me two sets of meds but they both stopped working and i just feel so hopeless. I have lost 20 pounds since finding out about the pregnancy and i cant do nothing but lay in bed all day since that seems to help. I tried the ginger ale, saltine crackers, small meals, fruits and veggies, but everything just makes me sick. if i dont eat within two-three hour time frame then i start vomiting my stomach acid .
