I didn't have a netti pot so I improvised and used a child's sippy cup. It worked great and I haven't had any allergies or headaches for two days now. The playtex sippy cup worked the best imo. My 7 yr old tried it also and is waiting for me to go fill the cup again so she can do the other side. My allergies have been so bad this year that I haven't been able to step outside without suffering for the rest of the day or a few days. Today I went outside several times...and our graw was mowed today. I am still breathing perfectly and have not taken any sinus remedies for two days.
