I have been on suboxone for 2 months and seems it made me so tired,he said try provigil so he told me take 200 mg a day. It has been 3 days but how long will it take to feel it work as good as he says it will ,I do not want to go back in a month and say it does not work and he will put me on the class 2 and I will get hooked on them but I have 5 kids and have to work so will the Provigil work
