I just wanted to post something to let others know how much benadryl has helped me. I am not recomending this for everyone (or anyone for that case), just letting you know. I have been diagnosed with Gastroparesis and have been FREAKING out. I have upset stomach daily and little appetite. I remembered from when I was in the hospital having a colon resection the nurse giving me benadryl. I have taken it a couple of times, only when it is really bad, and the syptoms have reduced. It also seems to help with my appetite, making me feel hungry and somewhat normal. I don't do this very often but I do feel that it is worth posting about.
Good luck to you all! Please be careful and talk to your doc before trying yourself.
