So sorry, was on a plane all day and just now turned on my computer. So by now hopefully everything is ok for you. Hopefully, (in a way) it was the ER or LA version as they release slowly, but for an extended period of time. So you could be feeling the effects for 10 or so hours. Fortunately, 60 mgs is within the maximum safe range for adults - so while you may feel like sh**, I think you will be ok.
Please get back and tell us how this ended. Most importantly for our own information - how long you felt the effects. And really importantly - if you did see a doc - what they did. Best wishes.
