I took my last Paxil this morning, but it was only half of one and I'm supposed to take it three times a day. I don't feel like going through any withdrawl symptoms, my presription is supposed to be ready for pick up today, but sometimes my doctor will forget to call or fax in the refill to the pharmacy. I'm also on klonopin which I take twice a day. How long will Paxil stay in my system before I go through wilthdrawl symptoms like anxiety from not taking it? I was gonna take a klonopin in replace of the paxil for my afternoon dosage, but I'm not.
