I'm a SAHM to DS 3.3 and DD 18.5 months and am currently 8ish weeks pregnant with number 3. my morning sickness/nausea/exhaustion is horrific this time round and 24/7. my DC are fighting and I can barely move without needing to lie down for 10 minutes to recover - how are other people doing this?! DH has been great doing all the childcare/food prep while he's here but I'm really struggling, have no family/friends to ask for help and I'm starting to feel really down 
Dr has prescribed cyclizine which worked fine yesterday but is barely touching my nausea today and I'm so bloated/have awful stomach acid/constipation - really not coping today
