igf and long work days?

I'm ready to make a purchase of igf for the first time. I'm 26 and a HD mechanic that works in the oilsands mining industry. my work schedule is 6 days on 6 days off 12 hour days. i get 3 breaks during the day so i get to eat 5 times a day. i've read quite a bit on here and people talk about how tired they get and needing naps etc. does this seem feasible? am i going to have serious issues staying awake? i like to keep my head in the game when at work whether i'm diagnosing or heavy lifts with crane. i've used eca before at work no real issues so possibly i could use that during the day. i would continue my workouts after work and would pin right after work on my way to the gym. i plan on pinning IM site specific 30-40mcg. goal would be work out 3 out of 6 work days on shift and 4 out of 6 days off shift, some of those workouts would mma training and a light weight days. should i scrap the mma training and keep it heavy weight specific?

any experience from people in a similar situation or any helpful input or ideas would be much appreciated.

Thanks Steve

I've never had any issues with being sleepy or anything. I take it in the morning, I take it at night, I take it in the afternoon... never have had an issue with IGF making me tired in any way. I think you'll be good to go, as long as you take it either first thing in the morning or 30 minutes pre-workout.

I only got tired a couple of times and it was immediately after applying. Some quick carbs fixed that right away though. Stay carbed up and it shouldn't be a problem, especially if you're not pinning it until after work.

If I haven't used igf in a while, it does make me feel a little more tired than usual when starting up again. Other than that, I only remember getting tired the first couple times I used it.

thanks for the answers,
Steve
