Stuffing

I bought some heavy cream to add to my gluttonous birthday plans. But I also never tried it.

I tend to drink it plain, just before bed. However I find that if I have more than 300ml it can make for heartburn or hot sweats. Obviously you may be able to tolerate it better than me (or worse).
In the UK we can't get Heavy Cream and so use Double Cream, which has a higher fat content (about 48% for DC compared with about 38% for HC). Maybe you could go higher than 300ml with HC but in either case it makes sense to work up to it. You will put yourself off altogether if you have too much too quickly and feel sick.
Whilst it is not sweet, I find it rather addictive and always look forward to my nightly dose.

I don't do the cream continuously as I have breaks from gaining sometimes due to life getting in the way. Over the last 3 weeks I have done 300-600ml double cream per day along with maybe 200g peanuts. This amounts to about 3000 cals in addition to normal eating. My weight has gone from 140Kg to 146.8 Kg (308 to 323 lbs). That's 5 lbs per week. I hope I can keep it up....
