"my pain specialist recommended this and after reading reviews i was so reluctant to take it, however i tried it and yes it did work 20mins later. i found myself relaxed, it was like i took a valium but when i woke up my heart rate was so low which wasn&#039;t normal for me. my hr is usually 65-80 but when i woke up i had a irregular heart beat of 43bpm. i thought i was going to have a panic attack cos of a sunken feeling in my chest. 
i suffer with ptsd, depression, anxiety and have crps so i do take 8 meds when necessary. will i continue taking 2mg melatonin? no, unless the blood test shows ur &quot;lacking melatonin&quot; i wouldn&#039;t recommend this. the number of complaints is quite alarming to me."
