im 16 years old and im perscribed to vyvanse and xanax. if i take my 70mg vyvanse and later on have a really bad crash will the xanax help stop it? im taking my vyvanse tomorrow morning before summer school and my friends will be at my house after. im taking the pill at about 6 in the morning and i get home around 3. im nervouse im going to have a really bad crash like i did one time and it was really bad. i might smoke butts with them after also. but if i do have a really bad crash will taking the xanax help stop it? my psych said it would but i havent really taken my vyvanse since that crash. so im not sure if i should take it or not cause i dont want to have a really bad crash. my xanax are .5 mgs so i usually take 2. will doing that help if im having a really depressing crash? sorry if this is confusing. i just dont want to have a crash but i really wanna take the vyvanse cause they make me feel soo good.
