On Tuesday I was dealing with head congestion so I took one dose of DayQuil because I didn’t have Sudafed. The following day I took a multi vitamin (I don’t usually take vitamins). Over the next couple of days, I’ve become increasing restless with racing thoughts, insomnia, stomach upset and burning skin on my arms and chest especially while trying to sleep. I’ve encountered this once before a couple of years ago when changing migraine medications too fast. Has anyone experienced anything like this? I’m wondering how long it could last. It’s scaring me and after my issues with my migraine med I never wanted to go through this again.
