Looking for a believable alternative reason for wearing sea bands at work😂

This is my second pregnancy- I’m nearing 8w and the nausea is starting to hit. 🤢 I’m wearing sea bands on my wrists to help (which it does seem to do) but am worried someone at work will ask what they are for if they see them (been wearing long sleeves to hide them but sometimes they peek out a bit). I’m def not ready to reveal my pregnancy to my coworkers! Anyone have any creative other reasons why I may be wearing them? I seriously doubt anyone at work really knows that they are for nausea and probably would believe whatever I tell them, but it should at least be plausible. 🤷🏼‍♀️ I was thinking something related to energy or exhaustion (since they know I have a 1 yr old at home)????? Any suggestions??

In case you don’t know what they are
