I sniffed a Desipramine Sat. night when I was drinking.Never done one before, Idk why I did this particular night either, but now, its Monday, and I feel like I have to use the bathroom, but I think Im like constipated.I mean I feel like I need to go, but nothing happens, I looked up side effects of Desipramine and it said Constipation was one of them.How long do you this will last? Its really freakin me out.
