My DH took his first escitalopram (SSRI) pill yesterday lunchtime and has spent the whole night shaking uncontrollably, unable to sleep, nauseous and feeling more miserable than ever. These are all side effects as mentioned in the packet but is it really going to last 2 wks? Please can anyone suggest anything I can do to help him in the meantime? My mum is buying some herbal sleep pills (GP said Kalms would be ok) as I think if he could sleep it would help and I can't leave him on his own.
