So I was prescribed sertraline nearly a year ago an for the first few days I took them I felt abit funny, like I was off my head all spaced out with tremors and a really bad gag reflex. I haven't taken them for nearly 4 months and last night I started them again... I took the first 50mg 19hrs ago an I felt spacey and weird as I did last time with tremors an warm tingles ect but Iv woke up today an the feeling has continued I'm having weird warm tingles my muscles keep clenching I feel abit out of it and I'm having some palpitations, really clenched jaw and just general weirdness. I don't remember feeling this bad before why is it effecting me like this ?? Is this normal I suppose I'm worried I'm having a adverse reaction to it and I'm scared of taking another one cos I still feel so off it !
