Sorry for the delay in following up on this post. I will give you my own personal experience and you can take it for what its worth. My very first day with it I screwed up. lol I took one about 1Pm in the afternoon just to see if it did anything with my focus,energy, etc. Well It did just that, I was ready to rock and roll in fact I was rocking and rolling until 3AM the next morning. First piece of advice always take it first thing in the morning. I would sum it up to this, In the gym or at work it gives you similar to tunnel vision on what you are currently doing. The only down side if you are in management as I am, and you have 20 different things going at once it is hard to multitask while on Provigil. You take one thing complete it and block the rest out, which can be good sometimes and not so good other times. As far as the gym goes I loved it, because I wouldn't be thinking about the next set I was just focused on the current reps I was doing at that time. I enjoyed the extra focus and energy. Normally by the time I work all day and get to the gym I am dragging ass so I take some pre work out to get me moving. In the days while I was taking I didn't need to take a pre workout. When I got to the gym I was still ready to get going. My normal schedule is up at 5:30 Am and in bed at 10:00Pm, while on I would get up at normal time and take one 200Mg about 8Am and wouldn't be ready for bed until 11:30 or 12:00.
I gave it a rest and haven't taken it since Wednesday 6/3. The day after I had a mild head ache after lunch took to Advil and was GTG. I have no sure prove it was because I didn't take it that day but am pretty sure it was since I do not hardly every have a headache unless I am ill. I was fine Thursday and Friday, now come yesterday I became insanely tired middle of the day Saturday. All I can figure is my body decided to catch up on the sleep it had missed will on Provigil. I am going to give it a break this week & then starting 6/15 I am going to take it only on weekdays for about two weeks and see how that goes. At the gym thursday I could tell a difference for sure, I was back to digging in my bag for pre work out for that extra boost to get me moving.
I didn't have any crazy side effects other than, for me 200MG will keep me awake for 13 or so hours. I also experienced a little headache once stopping of course I have no concrete prove if it was directly related. So I didn't experience any harsh sides. For me it defiantly helped focus and energy.
