Hi We just found out that my husband who is a diabetic has retrograde ejaculation which means his cum goes into his bladder instead of out of his penis. The doctor prescribed sudafed 1-2 pills every 4 hours. He took it starting on Friday and it's Saturday night now and he feels so weak, and very insomniac. Also Friday nigh while we had sex, he went limp and that has never happened before. Has anyone have this issue either RE or RE and sudafed use? Thank you.
