I have restlessness soon after taking Saphris that subsides after a couple of hours. I've been on the med for just a couple of days 2.5mg in the evening (which will certainly be increased); will this side effect resolve, become less, or is there something like an antihistamine that will help during that period of time? I take it in the evening because it makes me, helps me fall asleep. I take it for paranoia associated with PTSD. I'm a 57 year old male.
