Levall g symptoms and conditions

I have been taking Levall G off and on when needed, and it is an excellent nasal and respitoary decongestant. I accidentally took more than the prescribed dose one day and felt as if I were on Vicodin. I experienced a spurt of nausea but I drank some water and ate some crackers and then I was fine. After that, the Vicodin feeling started kicking in. I also felt very floaty. But it's hard with your coodination, so please, be careful. Just lie down!
