you cant move at all or are you slow? if youre slow, you take the pills from your inventory you got earlier
if youre frozen and cant move, i recommend closing the game and either closing all other programs and relaunching or restarting your computer and then only having the game open when you play again! some computers with slower processors dont like running the game if theres other programs open O: lemme know if this helps and if not i can look into it more!
