Occasionally, I will be doing a ride and feel like I really need to spit. Yes, spit. This has happened on a long ride, but it happened again today when doing a short, intense uphill ride. I had thought before that it was because I had over hydrated, but I really hadn't had a lot of my Cytomax drink today. Wondering if anyone else has experienced this or knows what might be the cause. Very unpleasant!
