Hello and hope you are doing well.
Venlafaxine can cause insomnia, nervousness, and tremor. Discuss your symptoms with your consulting doctor he may change the dose or the medications.
Hope this helped and do keep us posted.
Have you tried Imovane or Nitrazepam or even Sanval ? I went to UK and while I was there I got some of those, not sure if we have them in the US?
How long has it gone on? Me it been 18 days
