hello, i am 29 years old and have struggled with add/adhd and depression (undiagnosed) my whole life. about a month ago i went to my family doctor because of concerns over a recently developed rapid heart beat (95 at rest). while i was there i brought up my add and depression symptoms. he refered me to a psych. my psych told me that vyvanse would help my add and my depression. he started me on 30mg and had to move me up to 50mg after 2 weeks because it was wearing off half way through the day and i would get extremely tired. when i first started taking the drug i noticed that i was more clear headed and driven through the day. at the same time i noticed that my appetite had decressed,my throat stayed dry and i was having trouble falling asleep. i know that those three things are common side effects. eventually my ability to easily fall asleep came back, but my appetite has not. the appetite thing is not much of a problem because i always have been some what of an overeater. since starting the drug i have gone from 210 lbs to 192 lbs. this makes me worry a little bit but not much since i wanted to lose weight anyway. another side effect that i have noticed though is that i forget things. i forget words, names, where i put stuff and so on. i thought this medicine was supposed to make stuff like that better? also since i have started taking it my muscles (especially in my back) have started getting sorer and sorer. today my back is extremely sore as are my legs, and my feet and hands are cold, almost even numb. should i be worried? back to my pulse, my family doctor performed alot of test but said that he could not find the reason for it being so rapid. he told me to slowly ween myself off of caffine and eventually stop drinking any. i have reduced my caffine intake to about 24oz. a day, which is a vast improvement. but, my pulse is still 95 at rest. help!
