Drinking slim fast while pregnant

Sierra

Did anyone ever drink slim fast when they were pregnant? I’m supposed to be drinking meal replacement drinks with my meals for extra calories and nutrition because I’ve lost a lot of weight and I’ve been vomiting a lot. I usually just drink ensure but they didn’t have it when my fiancé went to the store so he got slimfast instead. It’s like the powder kind that you put in milk. I’ve just never drank it and I don’t even know if you can while pregnant
