So after reading a few topics on here, I learned that Benadryl is quite the miracle drug! It can help with nausea and anxiety as far as I understand it? So my question is, do all types of Benadryl work to relieve nausea and anxiety? I ask this because when I went to Tesco to buy some, there were some that lasted for 24 hours and some that didn't. Is there a certain ingredient that I need to look out for? I'd really like to try them out. Thanks.
