Hi, on November 13th at about 3:00 AM I was feeling under the weather so I took 30 mL of Tylenol Cold & Flu Severe which contains 20 mg of Dextromethorphan. I've heard that DXM interacts somehow with the serontonin levels in the brain. I need to know when it will be safe to start taking these 200mg timed release 5-HTP pills that I bought yesterday without something going wrong. If it's revelant I also took one tablet of Claritin-D extended release on November 13th at around 5:00 PM. Thank You.
