About this symptom

Low Alcohol Tolerance

Some women report that they have a much lower tolerance for alcohol very early in pregnancy - before they know they are pregnant or before they can even reliably test. (ie: one drink will make them feel tipsy or drunk) For some this is a really convincing sign.

I am 5 dpo. Last night I had a glass of wine with Hubby, and whoa! I felt like I had drunk the bottle! I have walking nausea today, ugh.

I’m 1 dpo and Usually 2 8% alcohol drinks get me drunk. I’ve already drank 2. Im not drunk? Could this be an opposite effect with pregnancy
